Non‐Bayesian Noun Generalization in 3‐ to 5‐Year‐Old Children: Probing the Role of Prior Knowledge in the Suspicious Coincidence Effect

It is unclear how children learn labels for multiple overlapping categories such as “Labrador,” “dog,” and “animal.” Xu and Tenenbaum (2007a) suggested that learners infer correct meanings with the help of Bayesian inference. They instantiated these claims in a Bayesian model, which they tested with preschoolers and adults. Here, we report data testing a developmental prediction of the Bayesian model—that more knowledge should lead to narrower category inferences when presented with multiple subordinate exemplars. Two experiments did not support this prediction. Children with more category knowledge showed broader generalization when presented with multiple subordinate exemplars, compared to less knowledgeable children and adults. This implies a U‐shaped developmental trend. The Bayesian model was not able to account for these data, even with inputs that reflected the similarity judgments of children. We discuss implications for the Bayesian model, including a combined Bayesian/morphological knowledge account that could explain the demonstrated U‐shaped trend.     

Religiosity, self-control, and virginity status in college students from the “Bible Belt”: a research note

Using a sample of college students (N = 904) from the "Bible Belt," this study examines the effect of religiosity and self-control on late adolescents' delay in initiating sexual intercourse or oral sex. Findings from logistic regressions provide evidence that for each one unit increase in self-control, the odds of a male remaining a virgin or of delaying oral sex increased by a factor of 1.82 and 2.84, respectively, while for females, the odds of not engaging in oral sex increased by a factor of 1.67. In addition to the effect of self-control, a one unit increase in religiosity results in the odds of a male remaining a virgin by a factor of 3.86 and 3.30, respectively. For females the odds are increased by a factor of 4.13 and 2.60, respectively. Mediation tests also provided evidence that self-control mediated the effects by religiosity on both dependent measures. Thus, both religiosity and self-control independently and additively function as key social control mechanisms that promote late adolescent health.     

Modeling and estimating recall processing capacity: Sensitivity and diagnostic utility in application to mild cognitive impairment

We investigate the potential for using latency-based measures of retrieval processing capacity to assess changes in performance specific to individuals with mild cognitive impairment (MCI), a reliable precursor state to Alzheimer’s Disease. Use of these capacity measures is motivated in part by exploration of the effects of atrophy on a computational model of a basic hippocampal circuit. We use this model to suggest that capacity may be a more sensitive indicator of the underlying atrophy than speed of processing, and test this hypothesis by adapting a standard behavioral measure of memory (the free and cued selective reminding test, FCSRT) to allow for the collection of cued recall latencies. Participants were drawn from five groups: college-aged, middle-aged, healthy elderly, those with a diagnosis of MCI, and a sample of MCI control participants. The measure of capacity is shown to offer increased classificatory sensitivity relative to the standard behavioral measures, and is also shown to be the behavioral measure that correlated most strongly with hippocampal volume.     

Applied Roles and the Future of Community Psychology

The roles for community psychologists have changed over the past several decades. These changes have implications for training, traditional academic roles, and the capacity of the field to maintain its integrity and further development. Changes in the scope of community psychology as a field as well as the roles of community psychologists are described with consideration of how they may affect participation in the field, retention of membership in SCRA, and potential directions for training.     

Empathy as dialectic imagination

Abstract

The importance of relationship processes for humanistic and psychodynamic therapists makes empathy a critical concept in psychotherapy. Experimental work suggests that learning occurs only when the subject is actively and cooperatively engaged in the learning process. Similarly, psychotherapy is only effective when the client is willingly active in the therapeutic process. A crucial aspect of the therapist's activity is empathic imagination, defined here as the use of “dialectic” thinking capacities‐the recognition of conceptual alternatives in a given situation. These processes are at the heart of a humanistic view of agency. The therapist's use of this capacity allows imaginative projection into aspects of the client's experience, helping the client to feel understood in the relationship and emboldened to consider new possibilities in life.     

Self-efficacy and affect responses to Sprint Interval Training

ObjectivesTo examine the influence of efficacious beliefs on affective states, enjoyment, and satisfaction after performing a maximal intensity exercise task (i.e. Sprint Interval Training (SIT).DesignAn experimental design was utilized and participants were randomized to a high self-efficacy feedback (HE), low self-efficacy feedback (LE), or no feedback control condition.MethodsCollege-aged men and women (n = 74) performed four 30-second maximal sprints, interspersed with 4-min breaks. Following each sprint interval, participants received either positive, negative or no feedback and SIT self-efficacy, affective states (i.e., positive well-being, psychological distress, fatigue), heart rate (HR), and ratings of perceived exertion (RPE) were assessed. Upon terminating the exercise session, enjoyment and satisfaction were assessed.ResultsThere was group equivalency in HR and RPE among participants of each group. The HE group had significantly less of a decline in SIT self-efficacy from pre to post SIT than both the LE and control groups, and reported significantly higher levels of exercise enjoyment than the other two groups. In addition, the HE and control groups reported significantly higher satisfaction than the LE group.ConclusionsWe recommend that exercisers receive positive feedback statements while performing SIT to minimize the decrease in SIT self-efficacy and to bolster feelings of enjoyment and satisfaction.     

Parental Responses to School-aged Children’s Sibling Conflict

The goals of this study were: (1) to describe and compare parental responses to school-aged siblings’ conflicts; (2) to explore the sibling relationship structural correlates of the parental responses; and (3) to assess the links between type of parental response and sibling relationship quality and children’s psychosocial and physical well being. One parent from eighty-two families (mothers = 68; fathers = 13; 1 missing) of firstborn (Mage = 9.84 years old) and secondborn (Mage = 7.16 years old) children completed an anonymous survey. Parents employed a child-centered strategy most often and sanctioned sibling aggression least often in response to siblings’ conflicts. Closer age spacing among siblings was related to parents’ sanction of physical aggression. Parental response type was associated with sibling relationship quality and children’s psychosocial and physical well being. The differential associations between parental response type, sibling experiences and children’s mental and physical well being are discussed.
