    When a cue is established as a reliable predictor of an outcome (A–O1), this cue will typically blocklearning between an additional cue and the same outcome if both cues are subsequently trained together(AB–O1). Three experiments sought to explore whether this effect extends to outcomes and wasinvestigated using the food allergist paradigm in human participants. In all 3 experiments, an outcomefacilitation effect was observed. That is, prior learning about an element of an outcome compound(A–O1) facilitated learning about a novel outcome when (A–O2) these outcomes were presented together(A–O1 O2) relative to a control stimulus that first received C–O3 trials prior to C–O1 O2 trials. InExperiment 2, however, participants were also presented with an additional set of control trials, whichwere presented during Stage II only and reliably predicted the outcome compounds. At test, participantsdisplayed more learning about these additional control trials relative to the blocked outcomes, thusdisplaying an outcome blocking effect alongside an outcome facilitation effect. In Experiment 3, aone-trial outcome blocking procedure was used to distinguish theoretical accounts of these findings. Thisprocedure revealed an outcome facilitation effect but not an outcome blocking effect. These results canbe understood in terms of an account derived from Wagner’s (1981) model. The implications of thesefindings are discussed

    Learned changes in outcome associability

    When a cue reliably predicts an outcome, the associability of that cue will change. Associative theories of learning propose this change will persist even when the same cue is paired with a different outcome. These theories, however, do not extend the same privilege to an outcome; an outcome’s learning history is deemed to have no bearing on subsequent new learning involving that outcome. Two experiments were conducted which sought to investigate this assumption inherent in these theories using a serial letter-prediction task. In both experiments participants were exposed, in Stage 1, to a predictable outcome (‘X’) and an unpredictable outcome (‘Z’). In Stage 2 participants were exposed to the same outcomes preceded by novel cues which were equally predictive of both outcomes. Both experiments revealed that participants’ learning toward the previously predictable outcome was more rapid in Stage 2 than the previously unpredicted outcome. The implications of these results for theories of associative learning are discussed

    Evaluating the effectiveness of a board game to learn biological psychology facts

    Using games in a classroom setting to help engagement and learning is becoming popular, but controlled investigations into the benefits of games are few. Games are potentially a way to incorporate retrieval practice into a class and garner subsequent benefits to memory. The aim of the present study was to investigate whether a board game assisted students to remember facts from a year one biological psychology module. Forty-seven participants (42 female, 5 male) took part in a seminar to test the hypothesis that playing the board game would enhance memory compared to taking part in a quiz. An experimental design was adopted with a between-subject factor (group: board game versus quiz) and two within-subjects factors: time of test (before the seminar, immediately after the seminar, 7-days after the seminar) and question type (seminar questions, i.e. questions contained in the game or quiz versus control lecture questions, i.e. questions that were not contained in the game or quiz but in a lecture). Contrary to the hypothesis, there were no differences in scores between the board game and quiz groups. We propose this is due to both groups having participated in retrieval practice during the game or the quiz. However, there was a significant main effect of time of test (scores immediately after the seminar increased) and a main effect of question type (scores were higher for seminar questions than control questions). The time of test x question type interaction was significant; post hoc analyses show that both groups scored higher on seminar questions compared to the control lecture questions in the after seminar test, and in the 7 days test. In conclusion, games can engage students and help them to remember complex material, but it is the use of retrieval practice specifically that aids memory. Our data show that retrieval practice can be equally effective in a board game or quiz, but students preferred the board game

    The role of prediction in learned predictiveness.

    Learning permits even relatively uninteresting stimuli to capture attention if they are established as predictors of important outcomes. Associative theories explain this “learned predictiveness” effect by positing that attention is a function of the relative strength of the association between stimuli and outcomes. In three experiments we show that this explanation is incomplete: learned overt visual-attention is not a function of the relative strength of the association between stimuli and an outcome. In three experiments, human participants were exposed to triplets of stimuli that comprised (i) a target (which defined correct responding), (ii) a stimulus which was perfectly correlated with the presentation of the target and (iii) a stimulus which was uncorrelated with the presentation of the target. Participants’ knowledge of the associative relationship between the correlated/uncorrelated stimuli and the target was always good. However, eye-tracking revealed that an attentional bias towards the correlated stimulus only developed when it AND target-relevant responding preceded the target stimulus. We propose a framework in which attentional changes are modulated during learning as a function the relative strength of the association between stimuli and the task-relevant response, rather than an association between stimuli and the task-relevant outcome

    High Schizotypy Predicts Emotion Recognition Independently of Negative Affect

    Introduction: Deficits in Emotion Recognition (ER) contribute significantly to poorer functional outcomes in people with schizophrenia. However, rather than reflecting a core symptom of schizophrenia, reduced ER has been suggested to reflect increased mood disorder co-morbidity and confounds of patient status such as medication. We investigated whether ER deficits are replicable in psychometrically defined schizotypy, and whether this putative association is mediated by increased negative affect.Methods: Two hundred and nine participants between the ages of 18 and 69 (66% female) were recruited from online platforms: 80% held an undergraduate qualification or higher, 44% were current students, and 46% were in current employment. Participants were assessed on psychometric schizotypy using the O-LIFE which maps onto the same symptoms structure (positive, negative, and disorganised) as schizophrenia. Negative affect was assessed using the Depression Anxiety and Stress Scale (DASS-21). Emotion Recognition of both positive and negative emotions was assessed using the short version of the Geneva Emotion Recognition Task (GERT-S).Results: Negative schizotypy traits predicted poorer ER accuracy to negative emotions (β = −0.192, p = 0.002) as predicted. Unexpectedly, disorganised schizotypy traits predicted improved performance to negative emotions (β = 0.256, p = 0.007) (primarily disgust). Negative affect was found to be unrelated to ER performance of either valence (both p > 0.591). No measure predicted ER accuracy of positive emotions. Positive schizotypy traits were not found to predict either positive or negative ER accuracy. However, positive schizotypy predicted increased confidence in decisions and disorganised schizotypy predicted reduced confidence in decisions.Discussion: The replication of ER deficits in non-clinical negative schizotypy suggests that the association between negative symptoms and ER deficits in clinical samples may be independent of confounds of patient status (i.e., anti-psychotic medication). The finding that this association was independent of negative affect further suggests ER deficits in patients may also be independent of mood disorder co-morbidity. This association was not demonstrated for the positive symptom dimension of the O-LIFE, which may be due to low levels of this trait in the current sample

    Increasing Condom Use and STI Testing: Creating a Behaviourally Informed Sexual Healthcare Campaign Using the COM-B Model of Behaviour Change

    Sexually transmitted infections (STIs) are a major public health challenge. Although theoretically informed public health campaigns are more effective for changing behaviour, there is little evidence of their use when campaigns are commissioned to the commercial sector. This study describes the implementation of the COM-B model to a sexual health campaign that brought together expertise from academics, sexual healthcare, and marketing and creative professionals. Insights were gathered following a review of the relevant academic literature. Barriers and facilitators to condom use and STI testing were explored with the use of the COM-B model and the Behaviour Change Wheel in a workshop attended by academics, behavioural scientists, healthcare experts and creative designers. Feedback on the creative execution of the campaign was obtained from healthcare experts and via surveys. Barriers to psychological capability, automatic and reflective motivation, and social opportunity were identified as targets for the campaign, and creative solutions to these barriers were collaboratively devised. The final sexual health campaign was rated positively in its ability to change attitudes and intentions regarding the use of condoms and STI testing. This study describes the implementation of the COM-B model of behaviour change to a public sexual health campaign that brought together academics, public and commercial sector expertise. The barriers and facilitators identified in this collaborative process represent potential targets for future public health communication campaigns

    The Developmental Trajectories of Children’s Reorientation to Global and Local Properties of Environmental Geometry

    The way in which organisms represent the shape of their environments during navigation has been debated in cognitive, comparative, and developmental psychology. While there is evidence that adult humans encode the entire boundary shape of an environment (a global-shape representation), there are also data demonstrating that organisms reorient using only segments of the boundary that signal a goal location (a local-shape representation). Developmental studies offer unique insights into this debate; however, most studies have used designs that cannot dissociate the type of boundary-shape representation that children use to guide reorientation. Thus, we examined the developmental trajectories of children’s reorientation according to local and global boundary shape. Participants aged 6–12 years were trained to find a goal hidden in one corner of a virtual arena, after which they were required to reorient in a novel test arena. From 10.5 years, children performed above chance when the test arena permitted reorientation based only on local-shape (Experiment 2), or only global-shape (Experiment 3) information. Moreover, when these responses were placed into conflict, older children reoriented with respect to global-shape information (Experiment 4). These age-related findings were not due to older children being better able to reorient in virtual environments per se: when trained and tested within the same environment (Experiment 1), children performed above chance from 6 years. Together, our results suggest (a) the ability to reorient on the basis of global and local-shape representations develops in parallel, and (b) shape-based information is weighted to determine which representation informs reorientatio
