Conditional And Biconditional Interpretations Of If-then Sentences: The Role Of Content And Context

Three experiments examined content and context effects on the interpretation of if-then sentences as either conditionals or biconditionals. In Experiment 1, participants were from four grade levels, ranging from kindergarten to grade 12. All grade levels gave biconditional interpretations to sentences in which the antecedent was necessary to the consequent but gave conditional interpretations to sentences in which the antecedent was only sufficient to the consequent. In Experiment 2, subjects were from three grade levels, ranging from grade 4 to university. All grade levels interpreted the same abstract if-then sentences as conditionals in one context but as biconditionals in another context. However, university students gave more conditional interpretations than did the other participants when the abstract sentences were presented without context. In Experiment 3, university students\u27 interpretations of if-then sentences were correlated with their ratings of the necessity of the antecedent to the consequent. In addition, conditional and biconditional if-then sentences led to different equivalence judgments and paraphrases. Considered together, the results of the three experiments provided consistent evidence that content and context are crucial factors in the interpretation of if-then sentences. These findings are discussed in relation to (a) theories of if-then reasoning, (b) age differences in reasoning, and (c) the design of reasoning instruction programs

A test of the somnolent mentation theory and the cognitive shuffle insomnia treatment

Insomnia affects about 33% of Americans according to Harvey & Tang (2003) who called for new cognitive treatments. We will report preliminary results from a test of (a) the Somnolent Mentation theory (SMT) of sleep onset (SO) and (b) a new cognitive treatment for insomnia, the cognitive shuffle (CS), derived from the SMT (Beaudoin, 2013, 2014). According to SMT, incoherent mentation characteristic of SO is not merely a side-effect of the SO period but promotes it, meaning it is somnolent. The SMT identifies several types of insomnolent mentation, which involve sense making (e.g., problem solving). SMT postulates counter-insomnolent mentation, thought patterns that interfere with insomnolent mentation. The CS is predicted to be both somnolent and counter-insomnolent (super-somnolent). Participants either engage in constructive worry Carney & Waters (2006) or in the CS using SomnoTest an iOS app developed by CogSci Apps Corp. (led by Beaudoin) based on mySleepButton®.&nbsp

Serial diverse imagining task: A new remedy for bedtime complaints of worrying and other sleep-disruptive mental activity

Introduction: A racing mind, worries, and uncontrollable thoughts are common bedtime complaints among poor sleepers. Beaudoin created a Serial Diverse Imagining task (SDIT) that can be used at bedtime to divert attention away from sleep interfering thoughts, An app randomly presents recordings of relatively concrete words one at a time with an 8-second interval between recordings during which the person creates and maintains a mental image of the word until the next recording prompts the next image and so on. Our study is an experimental test of SDIT compared to the standard treatment of Structured Problem-solving (SP) and to the combination of both treatments. A key feature of SP is that it must be done earlier than bedtime and requires about 15 minutes to do it.  SDIT, which is done at bedtime, does not have those constraints.  Method: 154 university students (137 female) who complained of excessive cognitive pre-sleep arousal were randomly assigned to receive SDIT, SP, or both.  At baseline, they completed Pre-Sleep Arousal Scale (Somatic and Cognitive), Sleep Quality Scale, Glasgow Sleep Effort Scale and Sleep Hygiene Index.  Depending on the measure, participants redid it one week and/or one month after starting the intervention.  (They also completed sleep diaries and appraisals of the interventions, which are omitted due to space). Results: Repeated measures ANOVAs indicated that cognitive and somatic pre-sleep arousal , sleep effort, and sleep quality improved significantly relative to baseline (p  < .001; Partial η2 = .43 to .71) even though sleep hygiene worsened ( p  < .001; Partial η2 =  .23). The latter finding is not unexpected because the baseline was done at the start of the academic term before the onset of academic pressures. The fact that we found sleep and arousal improvements in this context are notable. Conclusion: Beaudoin’s Serial Diverse  Imagining Task (SDIT) was as effective as Structured Problem-Solving (SP) in reducing pre-sleep arousal, sleep effort, and poor sleep quality.  One advantage of SDIT is that it can be done at bedtime, unlike SP.&nbsp

Sleep latency versus shuteye latency: Prevalence, predictors and relation to insomnia symptoms in a representative sample of adults

Shuteye latency (SEL) refers to the time spent performing activities in bed before attempting sleep. This study investigates (a) the prevalence, duration and predictors of SEL, (b) its association with insomnia symptoms (sleep onset latency [SOL], sleep quality and fatigue), and (c) the activities engaged in during SEL. A representative sample of 584 adults (18–96 years old) participated in an online survey. Respondents reported their SEL on weekday nights (Sunday to Thursday) and weekend nights (Friday and Saturday), and activities during SEL. One in five adults tried to sleep immediately at bedtime. Around 16% of respondents were awake >30 min on both weekday and weekend nights. Younger people and those with an eveningness preference reported longer SEL. Longer SEL corresponded with a progressive decline in sleep quality, increased SOL and more fatigue. Those with an SEL >30 min reported using both passive (e.g. television) and interactive (e.g. smartphone) media more frequently than respondents with an SEL < 30 min, but there was no difference between the groups for non‐screen‐related activities. Implications of SEL for measurements commonly used in sleep research are discussed. Shuteye latency may be symptomatic of how a modern lifestyle puts increasing pressure on sleep, but may also reveal a previously undocumented behaviour associated with insomnia symptoms.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/146592/1/jsr12737_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/146592/2/jsr12737.pd

Naturally occurring circadian rhythm and sleep duration are related to executive functions in early adulthood

Experimental sleep deprivation studies suggest that insufficient sleep and circadian misalignment associates with poorer executive function. It is not known whether this association translates to naturally occurring sleep patterns. A total of 512 of full-term-born members of the Arvo Ylppö Longitudinal Study [mean age = 25.3, standard deviation (SD) = 0.65] (44.3% men) wore actigraphs to define sleep duration, its irregularity and circadian rhythm (sleep mid-point) during a 1-week period (mean 6.9 nights, SD = 1.7). Performance-based executive function was assessed with the Trail-Making Test, Conners’ Continuous Performance Test and Stroop. The self-rated adult version of Behavior Rating Inventory of Executive Function was used to assess trait-like executive function. We found that performance-based and self-reported trait-like executive function correlated only modestly (all correlations ≤0.17). Shorter sleep duration associated with more commission errors. Later circadian rhythm associated with poorer trait-like executive function, as indicated by the Brief Metacognitive Index and the Behavior Regulation Index. Those belonging to the group with the most irregular sleep duration performed slower than others in the Trail-Making Test Part A. All associations were adjusted for sex, age, socioeconomic status and body mass index. In conclusion, naturally occurring insufficient sleep and later circadian rhythm showed modest associations with poorer executive function. Shorter habitual sleep duration was associated with lower scores of performance-based tests of executive function, and later circadian rhythm was associated mainly with poorer trait-like executive function characteristics. Our findings suggest additionally that sleep duration and circadian rhythm associate with different domains of executive function, and there are no additive effects between the two

Annual Research Review: Sleep problems in childhood psychiatric disorders – a review of the latest science

Background Hippocrates flagged the value of sleep for good health. Nonetheless, historically, researchers with an interest in developmental psychopathology have largely ignored a possible role for atypical sleep. Recently, however, there has been a surge of interest in this area, perhaps reflecting increased evidence that disturbed or insufficient sleep can result in poor functioning in numerous domains. This review outlines what is known about sleep in the psychiatric diagnoses most relevant to children and for which associations with sleep are beginning to be understood. While based on a comprehensive survey of the literature, the focus of the current review is on the latest science (largely from 2010). There is a description of both concurrent and longitudinal links as well as possible mechanisms underlying associations. Preliminary treatment research is also considered which suggests that treating sleep difficulties may result in improvements in behavioural areas beyond sleep quality. Findings To maximise progress in this field, there now needs to be: (a) greater attention to the assessment of sleep in children; (b) sleep research on a wider range of psychiatric disorders; (c) a greater focus on and examination of mechanisms underlying associations; (d) a clearer consideration ofdevelopmental questions and (e) large-scale well-designed treatment studies. Conclusions While sleep problems may sometimes be missed by parents and healthcare providers; hence constituting a hidden risk for other psychopathologies – knowing about these difficulties creates unique opportunities. The current excitement in this field from experts in diverse areas including developmental psychology, clinical psychology, genetics and neuropsychology should make these opportunities a reality
