A real-time criterion theory of duration discrimination

The common idea that a measure is taken of a duration stimulus over its temporal extent, and that the decision as to whether the stimulus is relatively long or short is based upon such a measure, is shown to be incorrect. Two experiments, which require speeded responding in duration discrimination and consider response latencies as well as response probabilities, demonstrate that the response that is made is determined by the outcome of a race between an internally timed interval, the criterion, and the presented stimulus. The onset of the stimulus triggers the criterion; if the criterion ends first, the response “long” is elicited. Duration discrimination is a matter of temporal order discrimination, and in the limit, “short” responses are simple reactions while “long” responses are time estimation responses. A specific model of the real-time criterion hypothesis is tested, and these initial tests generally confirm it. From this, it is concluded that errors in duration discrimination are due entirely to variability of the criterion and that afferent latencies are not necessarily variable. This adds additional evidence for the existence of deterministic afferent latencies.     

Burnout in counseling psychologists: Type of practice setting and pertinent demographics

Extent of burnout experienced by conseling psychologists and the relationship between levels of burnout and different types of practice settings, selected demographic and work-related variables were investigated in this study. Burnout was defind in terms of the Maslach Burnout Inventory (MBI) subsxales. Multiple regression anslyses were perforned on the data (n = 521). Counseling psychologists in private practice reported the lowest levels of burnout, while those employed in hospital settings reported the highest levels of Burnout. A positive relationship was found between hours of client contact per week and sense of personal accomplishment. Finally, an inverse relationship was reported between age and burnout, and males experienced greater depersonalization of clients than females.     

Family therapy and psychopathology: developments in research and approaches to treatment

The impact of family approaches in understanding and treating psychopathology is reviewed for the following disorders: schizophrenia, mood disorders, anxiety disorders, psychoactive substance use disorders, eating disorders, and conduct disorders in children. Family-oriented interventions are concluded to be useful in treating disorders when applied flexibly and multi-dimensionally and when used in conjunction with psychopharmacological or other valid individual treatment approaches.     

Social preference of female gerbils (Meriones unguiculatus) as influenced by coat color of males

Female gerbils (Meriones unguiculatus) of three distinct coat colors (agouti, black, and sandy or pink-eyed dilution) were tested in a Y-maze whose arms led to compartments containing unfamiliar male gerbils of varying coat colors. The stimulus animals were separated from the females by a Plexiglas door. The trials lasted for 2 min and each female was exposed to the following four combinations: two males of the same coloring as the female; one male of the same color and another of a different color from the female; both males of different color from the female. The number of crossings to the left and right arms was relayed by photocells to an IBM PC computer. The results indicate that agouti females preferred visiting the arm occupied by agouti males while those of the other coat colors showed no preference for the "wild-type" males. Instead, sandy and black female gerbils preferred to be in proximity with those of non-wild types.     

Behavioral assessment of avoidance in agoraphobia

Behavioral avoidance testing is a substantial addition to self-report questionnaires in the assessment of agoraphobia. However, the tests currently in use have drawbacks and limitations. A multitask behavioral avoidance test (M-BAT) is presented, designed to meet some of these problems. The test was administered to a group of 58 patients and proved to be reliable in terms of internal consistency. Concordance with self-report measures of agoraphobia indicated a high concurrent validity. In comparison with self-report questionnaires, the tests produced a slightly more conservative picture of gains achieved in treatment. Finally, the data revealed that the multitask test was more concordant with other measures of agoraphobia than a single-task test would have been.     

Integrity and the Value of an Integrated Self

What is integrity and why is it valuable? One account of the nature of integrity, proposed by John Cottingham amongst others, is The Integrated Self View. On this account integrity is a formal relation of coherence between various aspects of a person. One problem that has been raised against this account is that it isn’t obvious that it can account for the value of integrity. In this paper I will respond to this problem by providing an account of the value of an integrated self. I will do so by first looking closely at two examples from literature: John Sassal in John Berger’s A Fortunate Man and Tetrius Lydgate in George Eliot’s Middlemarch. Based on my comparison of these two case studies I will argue that an integrated self is valuable as it makes people more likely to act in line with their moral judgements.     

Gender roles and decision making among isiXhosa-speaking adolescents

This exploratory study examined gender roles and decision making among isiXhosa-speaking adolescents. Participants were a non-probability sample of 40 Grade 12 learners (females = 50%; aged between 17 and 24 years). Data were collected using identity status interviews and analysed thematically to profile the adolescents’ gender role identity statuses and related decisions. The findings suggest the adolescents to endorse gender roles somewhat discrepant to traditionalist roles in that females endorsed primary family financing provider and decision making, whereas the males were accepting of nurturing or carer roles in the family home. Gender role statuses and decision making among teenage isiXhosa appear to be shifting away from traditional roles towards modern thinking of gender equality.
