Developing a Sufficient Knowledge Base for Faces: Implicit Recognition Memory for Distinctive versus Typical Female Faces

Research on adults' face recognition abilities provides evidence for a distinctiveness effect such that distinctive faces are remembered better and more easily than typical faces. Research on this effect in the developmental literature is limited. In the current study, two experiments tested recognition memory for evidence of the distinctiveness effect. Study 1 tested infants (9- and 10-month olds) using a novelty preference paradigm. Infants were tested for immediate and delayed memory. Results indicated memory for only the most distinctive faces. Study 2 tested preschool children (3- and 4-year-olds) using an interactive story. Children were tested with an implicit (i.e. surprise) memory test. Results indicated a memory advantage for distinctive faces by three-year-old girls and four-year-old boys and girls. Contrary to traditional theories of changes in children's processing strategies, experience is also a critical factor in the development of face recognition abilities

Associations between body dissatisfaction and self-reported anxiety and depression in otherwise healthy men: a systematic review and meta-analysis

Introduction It is unknown whether male body dissatisfaction is related to anxiety and depression. This study investigates whether there is an association between body dissatisfaction and self-reported anxiety and/or depression in otherwise healthy adult males. Method A systematic review was conducted using Preferred Reporting Items for Systematic Reviews and Meta Analyses as the reporting guideline. Four databases including CINAHL complete, Health Source: Nursing/Academic Edition, MEDLINE and PsycINFO were searched for observational studies with a correlational design. Studies were appraised using the Appraisal tool for Cross-Sectional Studies to measure quality and risk of bias. Data were extracted from studies to analyse and synthesise findings using content analysis and random effects meta-analyses in male body dissatisfaction and anxiety, depression, and both anxiety and depression. Results Twenty-three cross-sectional studies were included in the review. Nineteen studies found positive correlations between male body dissatisfaction and anxiety and/or depression. Meta-analyses of Pearson’s correlation coefficients found statistically significant associations with body satisfaction for anxiety 0.40 (95% CI 0.28 to 0.51) depression 0.34 (95% CI 0.22 to 0.45) and both anxiety and depression outcomes 0.47 (95% CI 0.33 to 0.59). The quality appraisal found study samples were homogeneous being mostly ascertained through academic institutions where participants were predominantly young, Caucasian and with relatively high educational attainment. Measures of body satisfaction focused predominantly on muscularity and thinness. Discussion This study provides the first pooled estimates of the correlation between body dissatisfaction and anxiety and depression in men. Findings need to be interpreted with respect to the samples and outcomes of the included studies. It is recommended that future research should increase the diversity of men in studies. Studies should measure a wider range of body dissatisfaction types found in men. Conclusion The findings demonstrate that an association between male body dissatisfaction and anxiety and depression is likely to exist. Future research should address the temporal relationship between body dissatisfaction and anxiety and depression

The Boundaries of the Cognitive Phenotype of Autism: Social Cognition and Central Coherence in Young People with Autistic Traits and their First Degree Relatives

Autism is a behaviourally defined disorder. The impairments in social communication and repetitive behaviours are individually non-specific. The disorder has indistinct boundaries both with other psychiatric disorders and with normal personality types. At the cognitive level, groups of people with autistic disorder can be differentiated from people without the disorder by their ability to reason about beliefs and knowledge (Theory of Mind) and by tests of visual disembedding (central coherence). This study examined whether young people with some of the behavioural features of autism but not necessarily a diagnosis, would show this distinctive cognitive profile. In a sample of 60 young people with additional learning support needs, we found that those with high levels of autistic traits (n=40) showed the same cognitive profile as has been found in people diagnosed with autistic disorder. This supports the view that autism is an extreme on a continuum of cognitive traits. Given the highly heritable nature of autism, we hypothesised that the parents of the young people with autistic traits will also display these cognitive features. The results indicated that there was no difference between the groups of parents on an advanced test of social cognition. Parents of people with high autistic traits were more resistant to one of the visual illusions and saw fewer reversals of an ambiguous figure when IQ was statistically controlled. These results in a sample with a low genetic load suggest ambiguous figures will be important in delineating the broader cognitive phenotype of autism

Automated prompting technologies in rehabilitation and at home

Purpose - The purpose of this paper is to test the efficacy of an interactive verbal prompting technology (Guide) on supporting the morning routine. Data have already established the efficacy of such prompting during procedural tasks, but the efficacy of such prompting in tasks with procedural and motivational elements remains unexamined. Such tasks, such as getting out of bed in the morning and engaging in personal care, are often the focus of rehabilitation goals. Design/methodology/approach - A single-n study with a male (age 61) who had severe cognitive impairment and was having trouble completing the morning routine. An A-B-A'-B'-A?-B? design was used, with the intervention phase occurring both in an in-patient unit (B, B') and in the participant's own home (B?). Findings - Interactive verbal prompting technology (Guide) significantly reduced support worker prompting and number of errors in the in-patient setting and in the participant's own home. Research limitations/implications - The results suggest that interactive verbal prompting can be used to support motivational tasks such as getting out of bed and the morning routine. This study used a single subject experimental design and the results need to be confirmed in a larger sample. Originality/value - This is the first report of use of interactive verbal prompting technology to support rehabilitation of a motivational task. It is also the first study to evaluate Guide in a domestic context

The Effect of Perceptual Sensitivity on Face Recognition Abilities in Individuals with Autism: An Eye Tracking Study

Research demonstrates that individuals with autism process facial information in a different manner than typically developing individuals. Several accounts of the face recognition deficit in individuals with autism have been posited with possible underlying mechanisms as the source of the deficit in face recognition skills. The current study proposed a new account that individuals with autism are less sensitive at perceiving configural manipulations between faces than typically developing individuals leading to their difficulty recognizing faces. A change detection task was used to measure perceptual sensitivity to varying levels of configural manipulations involving the eye and mouth regions. Participants with and without autism, matched on chronological age, verbal IQ, performance IQ, full scale IQ, visual acuity, and gender, studied upright and inverted faces in a delayed same/different face recognition test. An eye tracker recorded eye gaze throughout the experiment. Results revealed a significant group difference with respect to detection accuracy. The control group was more accurate at detecting subtle changes between upright faces than the autism group, particularly with manipulations to the spatial relation of eyes. Furthermore, an analysis of detection accuracy within groups revealed that a greater proportion of participants in the control group were better at detecting differences at subtler levels of spatial manipulations. Eye tracking results revealed a significant group difference in number of fixations to relevant vs. irrelevant areas of interest; however, both groups utilized eye information more than mouth information to detect changes in both upright and inverted faces. Furthermore, there was some indication that eye gaze differed within groups, with a small proportion of individuals in both the autism and control groups demonstrating a bias to look more toward the mouth than eyes. Results are discussed with respect to featural vs. configural processing in autism and the use of eye vs. mouth information in face processing strategies by individuals with autism

The Diversity of Tone Languages and the Roles of Pitch Variation in Non-tone Languages: Considerations for Tone Perception Research

All languages employ consonants and vowels as discrete contrastive subcomponents of the basic timing units of words (syllables). These two classes of phonemes are used to differentiate between words, whose meanings can be categorically changed by switching even a single vowel or consonant, as in vs. or . They populate the lowest level of the phonological hierarchy, the segmental tier, and both classes are obligatory across spoken languages. But only some languages also make use of lexical tones, contrastive sub-syllabic fundamental frequency (pitch) variations referred to as tonemes (e.g., Jones, 1944), which for those languages comprise a third class of phonemic elements. Perceptual researchers often assume tones to be suprasegmental (e.g., So and Best, 2010, 2011, 2014; Liu et al., 2018; Poltrock et al., 2018), i.e., to extend across the consonants and vowels of the target syllable. While in a phonetic sense tones extend across the voiced segments of a syllable, however, such observations may not straightforwardly reflect the more abstract phonological properties of tones (e.g., see Wang, 1967; Hyman, 2011a,b). Indeed, several tone phonologists claim that lexical tones function as segments in tone languages (e.g., Lin, 1989; Duanmu, 1990, 1994). For the following paragraphs we adopt that phonological view that lexical tones function in tone languages at the segmental level, along with consonants and vowels. However, we return later to consider their phonological status and its relevance for understanding lexical tone perception by native and non-native listeners

Intergroup Dynamics in Speech Perception: Interaction Among Experience, Attitudes and Expectations

Experience, attitudes, and expectations have been identified as separate influences on speech perception and comprehension across groups. In this study, we investigate the interaction among these three variables. 58 Australia-born participants completed an online survey and a vowel categorization task. The survey examined participants’ experience with Vietnamese-accented English and their attitudes towards Asians. The vowel categorization task examined participants’ recovery of a Vietnamese-accented speaker’s intended vowels. Half of the participants were told to expect a Vietnamese accent whereas the other half were not. Results indicated that the relationship between listener expectations and group attitudes varied according to whether or not participants had experience with the Vietnamese accent. This interaction was most clearly reflected on the ‘book’ vowel. Compared to participants who did not expect a Vietnamese accent, had no experience with the Vietnamese accent, but positive attitudes towards the Vietnamese group, those who expected a Vietnamese accent showed a decrease in accuracy on ‘book’ categorization. A decrease in ‘book’ categorization accuracy was also found for those having experience with the accent but negative attitudes. In contrast, an increase in accuracy was found for those having no experience with the Vietnamese accent and negative attitudes towards the Vietnamese group, and those having experience with the accent and positive attitudes. We concluded that expectations, experience and attitudes interact in their relationship with speech perception

Psychometric properties of the Arabic version of the international consultation on incontinence questionnaire on long-term catheter quality of life

Aim To translate the International Consultation on Incontinence Questionnaire (ICIQ) Long-Term Catheter Quality of Life (LTCqol) questionnaire (ICIQ-LTCqol) questionnaire from English to Arabic and evaluate its psychometric properties. Background Currently, no tool for Arabic speaking patients is available to measure the quality of life in patients using long-term urinary catheters. Design Translation and psychometric assessment of questionnaire. Methods The internal consistency and construct validity of the translated Arabic version of the ICIQ-LTCqol were evaluated in a convenience sample of 141 participants recruited from a hospital in Egypt from April to September 2017. Test-retest reliability was assessed for a sample of 15 participants who completed this version at two-time points. Construct validity was assessed by factor analysis. Results The translated Arabic version of the ICIQ-LTCqol showed satisfactory test-retest reliability and internal consistency, with Cronbach’s α = 0·75. Confirmatory factor analysis confirmed the same two factors (‘catheter function’ and ‘lifestyle’) structure as found in the English version of the tool supporting the construct validity of the translated questionnaire. Conclusion This original and significant study allows, for the first time, researchers and clinicians working with Arabic speaking patients, the opportunity to evaluate the quality of life in long-term urinary catheter users

The Role of Words in Cognitive Tasks: What, When, and How?

The current review focuses on how exposure to linguistic input, and count nouns in particular, affect performance on various cognitive tasks, including individuation, categorization and category learning, and inductive inference. We review two theoretical accounts of effects of words. Proponents of one account argue that words have top-down effects on cognitive tasks, and, as such, function as supervisory signals. Proponents of the other account suggest that early in development, words, just like any other perceptual feature, are first and foremost part of the stimulus input and influence cognitive tasks in a bottom-up, non-supervisory fashion. We then review evidence supporting each account. We conclude that, although much research is needed, there is a large body of evidence indicating that words start out like other perceptual features and become supervisory signals in the course of development

The response of young adult smokers and nonsmokers in the United Kingdom to dissuasive cigarettes: An online survey

Introduction  The cigarette stick is an important communications tool as well as the object of consumption. We explored young adults’ responses to cigarettes designed to be dissuasive.  Methods  Data come from a cross-sectional online survey, conducted in September 2015, with 16-24 year old smokers and non-smokers (N=997) in the United Kingdom. Participants were shown images of a standard cigarette (white cigarette paper with imitation cork filter), a standard cigarette displaying the warning ‘Smoking kills’ on the cigarette paper, and an unattractively coloured cigarette (green cigarette paper and filter). They were asked to rate each of the three cigarettes, shown individually, on eight perception items, and to rate the three cigarettes, shown together, on how likely they would be to try them. Ordering of the cigarettes and questions, with the exception of the question on trial, was randomised.  Results  The eight perceptions items were combined to form a composite measure of cigarette perceptions. For smokers and non-smokers, the two dissuasive cigarettes (cigarette with warning, green cigarette) were rated significantly less favourably than the standard cigarette, and less likely to encourage trial. For cigarette perceptions no significant interaction was detected between cigarette style and smoking status or susceptibility to smoke among never smokers. A significant interaction was found for likelihood of trying the cigarettes, with dissuasive cigarettes having a greater impact with smokers than non-smokers.  Conclusions  This study suggests that dissuasive cigarettes may help to reduce the desirability of cigarettes.  Implications The cigarette stick is the object of tobacco consumption, which is seen every time a cigarette is smoked. It is also an increasingly important promotional tool for tobacco companies. In this study, young adults rated two dissuasive cigarettes (a green coloured cigarette and a cigarette displaying a health warning) more negatively than a standard cigarette, and considered them less likely to encourage product trial. Our findings suggest that it may be possible to reduce the desirability of cigarette sticks by altering their design, e.g. with the addition of a warning or use of an unattractive colour
