Laboratory instruments in the history of psychology

The importance of laboratory instruments as sources for the writing of the history of psychology is stressed, and illustrated through the use of examples where their study has been profitable. Most importantly, the role of the Hipp chronoscope in the reaction-time experiment is discussed, and the importance of various changes introduced into its design by James McKeen Cattell is shown. A photograph, first exhibited by the Department of Psychology of Clark University at the 1893 World's Columbian Exposition in Chicago is included, and further illustrates the importance of these instruments to historians.     

Psychosocial mediators of antiretroviral nonadherence in HIV-positive adults with substance use and mental health problems.

This study used data from 1,889 HIV-positive patients on antiretroviral (ARV) medications who participated in the HIV Cost and Services Utilization Study to investigate whether nonadherence to ARV medications among patients with mental health and substance use problems could be explained by difficulty getting and negative attitudes toward ARV medications, poor fit of the regimen with lifestyle, lack of instruction and cues for remembering the regimen from a health care provider, and poor support from others for taking ARV medications. Difficulty getting ARV medications and poor fit with lifestyle were significant mediators of nonadherence for patients with a probable psychiatric disorder. Difficulty getting medication was a mediator for heavy drinkers, and poor fit with lifestyle was a mediator for drug users who drank heavily. Further research is needed to identify and address the barriers to adherence in these populations.     

Evaluation of a statewide initiative to reduce expulsion of young children

This program evaluation study describes 3 years of implementation of Arkansas's BehaviorHelp (BH) system, a statewide expulsion prevention support system for early care and education (ECE). BH coordinates three tiers of supports to ECE professionals, including phone support, on‐site technical assistance (TA), and infant and early childhood mental health consultation (IECMHC). We examine differences in characteristics of those served across BH service tiers, describe short‐term case outcomes, and explore factors associated with expulsions. BH accepted referrals for 1,195 children in 488 ECE programs. The majority of referrals involved male children over the age of three, and most cases were assigned to the TA tier (68.5%). Cases assigned to receive IECMHC (28.4%) were more likely to involve children in foster care, receiving developmental therapies, and with higher rates of exposure to potentially traumatic events. The expulsion rate among referred children was 2.9%, and reported teacher engagement with the support process was high. Teachers receiving IECMHC services reported significant improvements in children's symptoms of emotional and behavioral problems. Exploratory analyses revealed that risk factors for expulsion included being a male, in foster care, in a lower quality ECE environment, and having a teacher with less training in social–emotional development.     

Exploring Counselor Experiences of Training in Relational Depth: An Interpretative Phenomenological Inquiry

Relational depth is an emergent counseling construct that captures the profound connection felt by client and counselor in moments of therapeutic encounter. We used interpretative phenomenological analysis to understand how 10 doctoral counseling students perceived curricular experiences designed to facilitate their ability to engage in relational depth. We identified the following themes: mutuality, counselor growth, externalized to internalized expectations, authenticity, impact of relational depth educational experiences, and relational depth reflection and articulation.     

Visual nesting of stimuli affects rhesus monkeys’ (Macaca mulatta) quantity judgments in a bisection task

Nonhuman animals are highly proficient at judging relative quantities presented in a variety of formats, including visual, auditory, and even cross-modal formats. Performance typically is constrained by the ratio between sets, as would be expected under Weber’s law and as is described in the approximate number system (ANS) hypothesis. In most cases, tests are designed to avoid any perceptual confusion for animals regarding the stimulus sets, but despite this, animals show some of the perceptual biases that humans show based on organization of stimuli. Here, we demonstrate an additional perceptual bias that emerges from the illusion of nested sets. When arrays of circles were presented on a computer screen and were to be classified as larger than or smaller than an established central value, rhesus monkeys (Macaca mulatta) underestimated quantities when circles were nested within each other. This matched a previous report with adult humans (Chesney & Gelman, Attention, Perception, & Psychophysics 24:1104–1113, 2012), indicating that macaques, like humans, show the pattern of biased perception predicted by ANS estimation. Although some macaques overcame this perceptual bias, demonstrating that they could come to view nested stimuli as individual elements to be included in the estimates of quantity used for classifying arrays, the majority of the monkeys showed the bias of underestimating nested arrays throughout the experiment.     

The child abusing family: I. Methodological issues and parent-related characteristics of abusing families

Abstract

The physical abuse of children by their parents is a family matter and should be viewed within the context of the family unit. Unfortunately, few child abuse studies have directly examined the family unit. Rather, most studies focus on characteristics of individual members of abusing families or on dyadic relationships within abusing families. Therefore, the present paper examines the family-related variables that might contribute to child abuse. This review is divided into two parts. Part I discusses methodological considerations and parent-related aspects of abusing families, including: characteristics of abusing parents, childhood experiences of abusing parents, marital relationships of abusing parents and the perceptions and expectations that abusing parents have of their abused children. Part II of this review, which will appear in a later issue, will cover child-related aspects of abusing families, parent-child interactions in these families, environmental conditions associated with child abuse and typologies of abusing families.     

Music and Language Skills of Children with Williams Syndrome

We examined music and language abilities in a group of children with Williams syndrome (WS, n = 19) and a comparison group of normal children (n = 19) equivalent for receptive vocabulary. Consistent with previous reports and the model of Nonverbal Learning Disabilities (Rourke, 1989), the children with WS scored better on verbal than performance measures of the WISC-III, and performance on simpler verbal tasks (e.g., receptive vocabulary) was superior to performance on more complex verbal tasks (e.g., comprehension). Performance on music tests was relatively good, being comparable to mental age based on receptive vocabulary and similar to that of the comparison group. Music and language abilities were moderately correlated for both groups of children. Compared to normal children, the WS group expressed greater liking of music and a greater range of emotional responses to music.
