Event-related potentials in a two-interval forced-choice detection task

In an attempt to elucidate the nature of the subject’s strategy in a two-interval forcedchoice auditory detection task, event-related potentials were studied at two intensities which yielded mean accuracies of 82% and 98%. Subjects reported the observation interval in which they judged the signal to be present and the confidence of the judgment. Principal components varimax analyses yielded four components: a CZ maximal P300, a Slow Wave, a slow negative shift, and a late negative component. The P300 amplitude findings suggest that different strategies are utilized for high-confidence and low-confidence detections. At high confidence, P300 amplitude is large for the observation interval in which the signal is presented, indicating a strategy involving serial independent detection. However, the P300 latency findings at high confidence suggest that absence of the signal in the first observation interval is nonetheless noted: P300 latency in response to signal presence is shorter for the second observation interval than for the first observation interval. At low confidence, P300 is small or absent for both observation intervals, indicating a deferred decision, presumably arrived at through comparison of the two percepts.     

The Relationship of School Climate Factors to Counselor Self-Efficacy

A survey of school counselors was conducted to measure the relationship of Bandura's (1977b) concept of self-efficacy with school climate, counselor roles, and a variety of demographic variables. Results indicated that supportive staff and administrators were the strongest predictors of high counselor efficacy expectancy. In addition, outcome expectancy for school counselor behavior was predicted by both a similarly high degree of support from staff and administrators and fewer nonrelated counseling activities performed by school counselors. Discussion of results and implications for research and practice are presented.     

When is it wrong to eat animals? The relevance of different animal traits and behaviours

Research suggests that animals’ capacity for agency, experience, and benevolence predict beliefs about their moral treatment. Four studies built on this work by examining how fine‐grained information about animals’ traits and behaviours (e.g., can store food for later vs. can use tools) shifted moral beliefs about eating and harming animals. The information that most strongly affected moral beliefs was related to secondary emotions (e.g., can feel love), morality (e.g., will share food with others), empathy (e.g., can feel others' pain), social connections (e.g., will look for deceased family members), and moral patiency (e.g., can feel pain). In addition, information affected moral judgements in line with how it affected superordinate representations about animals’ capacity for experience/feeling but not agency/thinking. The results provide a fine‐grained outline of how, and why, information about animals’ traits and behaviours informs moral judgements.

Sensory Modulation for People with Anxiety in a Community Mental Health Setting

Anxiety is a common mental health issue involving cognitive and physiological hypersensitivity to threat. It negatively affects occupational participation. Sensory modulation intervention aims to use calming sensory input to manage the hypersensitivity and physiological arousal associated with anxiety. The empirical evidence for using sensory interventions for anxiety, however, is limited. This mixed methods single subject case design explored the effectiveness of a 6-week sensory modulation intervention for reducing anxiety and improving occupational participation. Results showed significant reduction in anxiety and improved participation, providing further evidence that sensory modulation is an effective approach for the self-management of anxiety.     

Justice for whom, exactly? Beliefs in justice for the self and various others

The present studies examine why people think the world is more just to themselves than to others generally. Beliefs in justice for the self were uniquely associated with psychological adjustment, consistent with the theoretical motive to believe in justice for the self (Studies 1 and 2). However, this "justice motive" did not appear to affect the relative strength of justice beliefs. Instead, self-other differences in justice beliefs appeared to reflect objective assessments of the justice received by various demographics. Undergraduates believed the world to be more just to themselves than to others but not their undergraduate peers specifically (Study 1). Participants of both genders believed the world to be more just to men, and to themselves, than to women (Study 2). Women did not exempt themselves individually from injustice but believed, similar to men, that undergraduate women receive as much justice as men (Study 3).     

How does the Health Action Process Approach (HAPA) Bridge the Intention–Behavior Gap? An Examination of the Model's Causal Structure

The health action process approach (HAPA) is attracting increasing interest from researchers who want to predict, explain, and change health-related behaviors. The main aim of this commentary is to examine the causal structure of the continuum version of the HAPA (HAPA-C), and, in particular, to consider the implications of this structure for the claim that the theory helps to bridge the intention–behavior gap. The article discusses, in turn, mediators of the intention–behavior relationship, additional proximal determinants of behavior, moderators of the intention–behavior relationship and implications for intervention. The commentary may contribute to a better understanding of the HAPA-C and to its further development.
L'Approche des Processus d'Action en faveur de la Santé (HAPA) suscite de plus en plus d'intérêt de la part des chercheurs qui souhaitent prédire, expliquer et modifier les comportements relatifs à la santé. L'objet de ce commentaire est l'examen de la structure causale de la version continuum de l'HAPA (HAPA-C) et, en particulier, de prendre en considération les implications de cette structure dans la prétention de la théorie à combler le fossé intention–comportement. L'article aborde successivement les médiateurs de la relation intention–comportement, les déterminants immédiats additionnels de la conduite, les modérateurs de la relation intention–comportement et les retombées pour les interventions. Ce commentaire peut contribuer à une meilleure compréhension de l'HAPA-C et à son futur développement.     

Age and culture modulate object processing and object—scene binding in the ventral visual area

Behavioral differences in the visual processing of objects and backgrounds as a function of cultural group are well documented. Recent neuroimaging evidence also points to cultural differences in neural activation patterns. Compared with East Asians, Westerners’ visual processing is more object focused, and they activate neural structures that reflect this bias for objects. In a recent adaptation study, East Asian older adults showed an absence of an object-processing area but normal adaptation for background areas. In the present study, 75 young and old adults (half East Asian and half Western) were tested in an fMR-adaptation study to examine differences in object and background processing as well as object—background binding. We found equivalent background processing in the parahippocampal gyrus in all four groups, diminished binding processes in the hippocampus in elderly East Asians and Westerners, and diminished object processing in elderly versus young adults in the lateral occipital complex. Moreover, elderly East Asians showed significantly less adaptation response in the object areas than did elderly Westerners. These findings demonstrate the malleability of perceptual processes as a result of differences in cohort-specific experiences or in cultural exposure over time.
