Reevaluation of things past

The ability of rats to reevaluate previously presented information in light of subsequently provided information was evaluated using a CER (conditioned emotional response) procedure. In Experiment 1, rats suppressed responding to a compound light + tone stimulus that was repeatedly paired with shock. Groups of rats were then presented with only one element of the compound (the tone), either presented alone or paired with shock, for 15 days. During this 15-day period, two control groups received trials with the shock alone or neither stimulus nor shock. All of the rats were then tested with the other element of the compound (the light). Rats that had received the tone paired with shock during the intervening training continued to suppress to the light, whereas rats that had received the tone alone showed rapid extinction of the CER to light. The control groups showed that this effect was not due to the number of shock presentations received. A subsequent experiment also demonstrated that these results were not due to nonspecific stimulus effects. Apparently, a subsequent change in the associative strength of one element results in a similar change to the other element of a previously established compound stimulus.     

Comments on Thomas and Jamison's “a test of the X-linked genetic hypothesis for sex differences on Piaget's water-level task”

In this paper H. Thomas and W. Jamison's (Developmental Review, 1981, 1, 274–283) formulation and evaluation of an X-linked genetic model for explaining male superiority on Piaget's water horizontality task is examined. Criticisms are leveled against (1) the suitability of the model invoked for explaining the sex difference found, (2) the power of the statistical test used to evaluate the model, and (3) the appropriateness of their correction factors. A research strategy for advancing our understanding of the sex difference in performance at this task is suggested.     

Effects of setting and number of observations on generalizability of parent-child interactions in childhood obesity treatment

The generalizability of behaviors across observational conditions is a critical issue in behavioral assessment. Generalizability theory was used to examine two aspects of audio recorded parent-child interactions recorded over 6 days of home measurement and 1 day of laboratory measurement in a behavioral treatment program for childhood obesity. Families audiotaped parent-child home meetings during which they reviewed self-monitored diet and exercise records that were coded for the following types of interactions: praise statements, negative statements, prompts for new behaviors, and statements promoting problem solving. A similar meeting was audiotaped in our laboratory. The first question explored was the number of measurements needed to generalize to the universe of the six home measures. Results showed an increase in generalizability over measurements for each behavioral category. Using generalizability coefficients of .60 or more, praise, negative comments and prompts, respectively, could be reliably observed based on 1, 4, or 4 days of measurement. Second, the effects of setting (laboratory versus home) were assessed for 1 day of measurement in each environment. Again using generalizability coefficients of .60, generalizability analysis showed that the lab setting could not be generalized to the home setting based on 1 day of measurement, with generalizability coefficients ranging from .27 for negative comments to .57 for praise. Results suggest that 4 days of behavioral assessment in the home can be used to establish generalizable data for all the dependent measures studied. However, generalizability coefficients suggested that 1 day of laboratory measurement was not adequate to generalize to typical home behavior.This research was supported in part by Grant NIH HD 23713 awarded to the third author.     

Binary-choice decision time depends upon cerebral hemisphere and nature of task

Binary-choice paradigms are classificatory problems of basic importance to the understanding of elementary decision processes. Generally when subjects decide if two visual stimuli are identical or differ by as little as one element, the decision of "Different" takes longer. This finding is unexpected as decisions of "Different" should not require an exhaustive matching of elements. Using stimulus presentation to the right and left cerebral hemispheres, the right hemisphere initiated fast selections of "Same" for figural material and alone was responsible for the "Same"/"Different" response differential. Exp. 1 (n = 22) gave no differences for same-different, unilateral-bilateral stimulation, and left-right hemispheres. Exp. 2, using word meaning as the binary-choice task, also showed faster decisions for "Same" but a different left-hemisphere-dependent strategy. The nature of information processing in relation to binary-choice tasks is discussed and the utility of bihemispheric paradigms is demonstrated.     

Evaluation of a Measure of Self-Esteem Based on the Concept of Unconditional Self-Regard

A measure of unconditional self-regard (USR) derived from Rogerian (client-centered) theory was evaluated in four studies. Results indicated that USR was highly reliable and was strongly related to other measures of self-esteem and negatively related to depression, anxiety, and symptoms of psychological distress. The measure was significantly related to the control and commitment dimensions of psychological hardiness but not to its challenge dimension. Evidence for discriminant validity was provided by findings that USR was unrelated to social desirability or private self-consciousness. Finally, female students'self-regard was significantly related to the unconditional positive regard they reported receiving from their mothers. Other correlations between self-regard and perceived regard from others, although nonsignificant, were often large in absolute value. Implications for counseling interventions are discussed.     

Developmental and Adjustment Issues of Gay, Lesbian, and Bisexual Adolescents: A Review of the Empirical Literature

Various studies have reported adjustment problems experienced by gay, lesbian, and bisexual (GLB) adolescents. A primary purpose of this paper is to critically review this literature. Difficulties that have been studied include past suicide attempts, substance use and abuse, conduct problems, and academic concerns. For example, a considerable number of GLB youth report a history of suicide attempts, with prevalence rates ranging from 11 to 42%. However, among other methodological concerns, studies in this area have not used a comparison sample of heterosexual youths. Characteristics of development particular to GLB adolescents are described, the empirical research on adjustment issues is reviewed, and potential risk and protective factors for GLB youths are discussed.     

Freeze-Frame: a new infant inhibition task and its relation to frontal cortex tasks during infancy and early childhood

The current study investigated a new, easily administered, visual inhibition task for infants termed the Freeze-Frame task. In the new task, 9-month-olds were encouraged to inhibit looks to peripheral distractors. This was done by briefly freezing a central animated stimulus when infants looked to the distractors. Half of the trials presented an engaging central stimulus, and the other half presented a repetitive central stimulus. Three measures of inhibitory function were derived from the task and compared with performance on a set of frontal cortex tasks administered at 9 and 24 months of age. As expected, infants' ability to learn to selectively inhibit looks to the distractors at 9 months predicted performance at 24 months. However, performance differences in the two Freeze-Frame trial types early in the experiment also turned out to be an important predictor. The results are discussed in terms of the validity of the Freeze-Frame task as an early measure of different components of inhibitory function.     

Spirituality as a Resiliency Quality in Xhosa-speaking Families in South Africa

The purpose of this qualitative study was to explore spirituality as a characteristic of family resilience in Xhosa-speaking families in South Africa. A parent, and in some cases an adolescent, represented each of the 51 families that participated. Participants were expected to respond to three open-ended questions regarding their family and identify factors or strengths that had recently helped their family. The results indicate that spirituality is an important coping resource. The core theme of spirituality consists of six related categories that facilitated the successful adaptation of the participating families after a crisis. These categories are Gifts from God; Guidance; God's Works; God's Plan; Prayer; and Faith.     

The Impact of Alcohol on Negotiator Behavior: Experimental Evidence1

Business‐related drinking is an important organizational and managerial activity with particular relevance to the negotiation process. This paper investigates the influence of a moderate amount of alcohol on negotiator behavior and negotiated outcomes. We conducted 2 negotiation studies involving inebriated and sober participants, and found that inebriated negotiators used more aggressive tactics, made more mistakes, and reached less integrative agreements than did sober negotiators. Across both studies, we found that inebriated negotiators were unaware that alcohol had affected their negotiations.
