Functional analysis and treatment of verbal perseverations displayed by an adult with autism

The function of perseverative speech for an adult man who had been diagnosed with autism and mental retardation was examined. Results showed that verbal perseverations were maintained by social attention. An intervention consisting of differential reinforcement of appropriate verbal responses and extinction of perseverative verbal responding was effective in decreasing verbal perseverations.     

Intended and unintended effects of explicit warnings on eyewitness suggestibility: Evidence from source identification tests

Previous studies have shown that source identification (ID) tests reduce, and in some cases eliminate, eyewitness suggestibility errors. The present study showed that the suggestibility errors participants committed on a source ID test were further reduced when they were given the explicit postwarning that the experimenter was trying to trick them. These postwarnings reduced suggestibility to the same extent as prewarnings, and they did so for both once and repeatedly suggested items. In addition, the benefits of the pre- and postwarnings persisted when participants were retested 1 week later, but only if the suggestions had been repeated. For once-suggested items, the warning had the unintended effect of improving old/new recognition of the suggested information at retest, an effect that offset the improvements in source discrimination accuracy conferred by the warning. The advantages of using source ID tests for investigating group differences in eyewitness suggestibility are discussed.     

Tops are more salient than bottoms.

Past research has verified that observers assume that objects are reliably oriented with respect to a gravitationally centered coordinate system. Observers also appear to attend more to specific parts of objects, like faces, that typically are closer to the top. In the present work, we explored whether or not observers have a generic bias to view tops as being more salient than bottoms. In three experiments, observers indicated whether random shapes appeared to be more similar to comparison shapes that shared identical tops rather than bottoms. Observers exhibited a reliable tendency to match figures with similarly shaped tops. Matching choice was also a function of global shape attributes such as axis of elongation or size. The findings are consistent with the notion that, in nature, tops tend to be the most visible part and to provide the best information with respect to important aspects of objects such as animal intentionality and artifact functionality.     

Putting “Positive” and “Psychology” In Perspective: The Role of Indian Psychology

Rao (this issue) offers a trenchant critique of the field of positive psychology. He clearly shows the way positive psychology, as it has been thus far considered, is clearly a product of a Westernized psychology. He goes further though and proposes that some of the limitations of positive psychology might be addressed by considering the insights of Indian indigenous psychology. In this commentary I suggest that these limitations of positive psychology can be fruitfully framed by considering the nature of the self and the nature of the positive or good that any understanding of positive psychology must presuppose.     

Perceptual hysteresis in the judgment of auditory pitch shift

Perceptual hysteresis can be defined as the enduring influence of the recent past on current perception. Here, hysteresis was investigated in a basic auditory task: pitch comparisons between successive tones. On each trial, listeners were presented with pairs of tones and asked to report the direction of subjective pitch shift, as either “up” or “down.” All tones were complexes known as Shepard tones (Shepard, 1964), which comprise several frequency components at octave multiples of a base frequency. The results showed that perceptual judgments were determined both by stimulus-related factors (the interval ratio between the base frequencies within a pair) and by recent context (the intervals in the two previous trials). When tones were presented in ordered sequences, for which the frequency interval between tones was varied in a progressive manner, strong hysteresis was found. In particular, ambiguous stimuli that led to equal probabilities of “up” and “down” responses within a randomized context were almost fully determined within an ordered context. Moreover, hysteresis did not act on the direction of the reported pitch shift, but rather on the perceptual representation of each tone. Thus, hysteresis could be observed within sequences in which listeners varied between “up” and “down” responses, enabling us to largely rule out confounds related to response bias. The strength of the perceptual hysteresis observed suggests that the ongoing context may have a substantial influence on fundamental aspects of auditory perception, such as how we perceive the changes in pitch between successive sounds.     

Assessing Male Batterers With the Personality Assessment Inventory

Despite the importance of the assessment of ego strength for appropriate assignment of clients for psychotherapy and/or rehabilitation, existing techniques have not fulfilled expectations. A method for assessing ego strength through the Rorschach Test independent of clinical criterion is proposed. In addition to certain variables of Klopfer's RPRS (M+, FM+, FC+ plus CF+), sharply preceived space responses are included. They constitute a highly intercorrelated global measure of ego strength and are also highly correlated to a relatively independent Rorschach variable of global ego efficiency, i.e. integrated whole responses. In accordance with prediction, non-controlled color responses as well as accuracy of form perception did not correlate in a non-clinical sample with either measure of ego strength.     

Understanding the Behavioral Determinants of Mental Health Service Use by Urban, Under-Resourced Black Youth: Adolescent and Caregiver Perspectives

Black adolescents with mental health problems are less likely than non-Black adolescents with mental health problems to receive treatment, primarily for non-financial reasons including negative perceptions of services and providers, and self-stigma associated with experiencing mental health problems. To better understand these obstacles, 16 adolescents and 11 caregivers, recruited from two K-8th grade elementary-middle schools, participated in four focus groups guided by the unified theory of behavior to explore mental health help-seeking behaviors and perceptions of mental health services. In the focus groups, caregivers acknowledged more positive attitudes about seeking mental health services than adolescents, but both expected the experience of actually doing so to be negative. Adolescents and caregivers also acknowledged social norms that inhibit their mental health help-seeking. Therefore, we conclude that interventions targeting expectancies and social norms might increase the connection of urban, under-resourced Black adolescents and their families to mental health services, and be particularly important given the long-term consequences of untreated mental health problems for this group.     

Acoustic confusion of digits in memory and recognition

It has been shown that, contrary to current opinion, digits do not confuse arbitrarily and that similar patterns of confusion are observed in memory and auditory recognition tasks. Two alternative measures of stimulus similarity are compared.     

DISABILITIES TO EMPLOYMENT AMONG EX-ADDICTS

Are ex-addicts poor employment risks? To answer this question, the employment responses of male and female ex-addict clients serviced by a state narcotic aftercare program were studied. Comparison of the two groups found differences in their job-seeking behavior and their social and deviant behavior characteristics. The results support the view that ex-addicts are handicapped persons. Their varying potentials for obtaining legitimate employment are isolated and reported in this article.
