THE USE OF PROMPTS TO ENHANCE VICARIOUS EFFECTS OF NONVERBAL APPROVAL

The effect of nonverbal teacher approval (physical contact in the form of patting approvingly) delivered to target subjects on the attentive behavior of adjacent peers was examined in a special-education classroom. In a reversal design, two pairs of moderately retarded children were exposed to nonverbal approval, with only one subject in each pair receiving approval. In different phases, nonverbal approval was delivered alone or in conjunction with a verbal prompt directed to the adjacent peer or to the class as a whole. The prompt was designed to make salient the target subject's attentive behavior and the nonverbal reinforcing consequences that followed. Providing contingent nonverbal approval alone consistently altered attentive behavior of the target subjects but did not alter the attentive behavior of adjacent peers. However, accompanying nonverbal approval with a verbal prompt did increase attentive behavior of nonreinforced peers.     

The effect of selective adaptation on the identification of speech sounds

An experiment was performed to determine the effect of selective adaptation on the identification of synthetic speech sounds which varied along the phonetic dimensionplace of articulation. Adaptation with a stimulus of a particular place value led to a reduction in the number of test stimuli identified as having that place value. An identification shift was obtained even when the acoustic information specifying place value for the adapting stimulus had virtually nothing in common with the information specifying place value for any of the test stimuli. Removing the vowel portion of an adapting stimulus eliminated identification shift only when the resulting stimulus was no longer perceived as speech-like. The results indicate that at least part of the adaptation effect occurs at a site of phonetic, not merely acoustic, feature analysis.

     

Kinship Support and Academic Efficacy Among College Students: A Cross-Sectional Examination

The study examined whether relationships with extended kin were related to higher levels of mental health and academic functioning among college students. Specifically, the study tested whether perceived emotional support from extended (non-nuclear) family was related to self-esteem, psychological distress, and academic efficacy and dedication above and beyond relationships with one’s primary caregivers, and whether these associations varied by class year in college. The sample consisted of 530 students (average age = 20.82), at a public, four-year university. The results revealed that freshmen and seniors who reported high levels of positive relationships with their extended kin also reported higher levels of academic-efficacy and dedication, as well as lower levels of psychological distress. However, the relation between kin emotional support and these outcomes were not significant for sophomores and juniors. There was also a significant association between kinship support and self-esteem for participants in all four class levels. The study underscores the need to examine extended social support systems among college students, above and beyond those maintained with primary caregivers, as well as the dynamic nature of family support during young adulthood.

Resurgence is greater following a return to the training context than remaining in the extinction context

The present study examined whether resurgence of a previously reinforced target response upon removing alternative reinforcement would be greater when (1) returning to the original training context (ABA context changes) versus (2) remaining in the analogue treatment context in which the alternative response was differentially reinforced (ABB context changes). Experiment 1 arranged reinforcement of button pressing with points exchangeable for money in university students. Experiment 2 arranged reinforcement of lever pressing with food for rats. Experiment 3 arranged reinforcement of responses to a touchscreen with small bites of food with children diagnosed with ASD. Overall, resurgence of target responding tended to be greater when returning to the original training context (A) than when remaining in the analogue treatment context (B). These findings suggest context changes with differential reinforcement treatments could exacerbate the recurrence of problem behavior resulting from reductions in treatment integrity through failure to reinforce appropriate behavior.     

Did You Say He Has a Hitler Mustache?: Analytic Vulnerability and Destabilization in the Face of Trauma

This paper looks at analytic vulnerability and destabilization through a detailed clinical example. There are different ways in which we may be vulnerable with our patients. In this paper I describe the raw and sudden vulnerability of allowing ourselves to be in a place of not knowing when both patient and analyst are unable “to see.” I describe an experience in which I lose my ability “to see,” both literally and metaphorically, while in session with a patient who is unable “to see” because she has dissociated her experience of loss and her experience of a sense of danger when in the presence of her stepfather. I link this clinical experience to the patient’s dissociated feelings and to my history of intergenerational trauma as well to current cultural violence and hate.     

Addressing two blind spots of commonly used experimental designs: The Highly‐Repeated Within‐Person approach

Two well documented but still neglected blind spots of often‐used study designs limit a researcher's ability to make inferences about psychological phenomenon. First, typical designs focus on effects of conditions at the group level and are not able to assess the extent to which effects characterize each participant in the study. This blind spot can lead to erroneous (or incomplete) conclusions about the effects of manipulations both for a given participant and at the group level. Second, commonly used research designs often use a limited sample of stimuli, constraining conclusions to the particular stimuli. This blind spot can lead to non‐replication when different stimuli are used. We propose that the Highly‐Repeated Within‐Person (HRWP) approach helps mitigate these limitations. Using a study on the effects of anti‐smoking messages, we illustrate how the HRWP approach helps alert researchers when the conclusions at the group level may not apply to all (or any) participant, quantifies the heterogeneity of effects of manipulations across people, and increases confidence regarding the generalizability of the effects. We discuss how the HRWP approach may help conceptualize issues of replicability in a new light.
