Effects of training intensity on observers' ratings of anxiety, social skills, and alcohol-specific coping skills

Few studies have addressed the amount of training needed to obtain reliable ratings in behavioral observation data. The current study examined the effects of differing intensities of frame-of-reference (FOR) rater training on observers' ratings of anxiety, social skills, and alcohol-specific coping skills in community volunteers with and without social anxiety and alcohol use disorders. Interrater reliability was assessed by comparing three training conditions (no-training, moderate FOR, and intensive FOR) on discrepancies between raters'scores and the strength of association between raters'scoring patterns. The discrepancies between raters' scores were significantly larger in the control condition than in the intensive and moderate training conditions. Generally, small and nonsignificant differences were found between intensive and moderate training's discrepancy scores. Strength of association results showed significantly lower correlations in the control group compared to the intensive group. However, these correlational results showed less consistent differences between the moderate and other training conditions; differences when found were in the expected directions. Study findings suggest that differing training intensities can affect rating scores and that interrater reliability may be meaningfully assessed through multiple methods.     

Contact and the personal/group discrimination discrepancy in an Inuit community

The personal/group discrimination discrepancy involves disadvantaged group members rating discrimination directed at their group considerably higher than ratings of discrimination aimed at themselves personally as members of that group. This robust phenomenon has been found in samples of women, African Americans, and aboriginal people. In the present study, the authors used a sample of Inuit from a remote Arctic community to confirm the perceived discrepancy. However, ratings for perceived group discrimination were surprisingly low. The authors argue that geographical isolation may have led Inuit to be unaware of the impact of discrimination on their lives. In support of this argument, findings showed that group discrimination ratings were higher for Inuit who did have contact with mainstream Canadian culture. Implications for the traditional contact hypothesis are discussed.     

Women and the Social Movements of the 1960s: Activists, Engaged Observers, and Nonparticipants

Many women in the generation that attended college during the 1960s have reported that they were influenced by the social movements of that era, even women who did not participate in them. In addition to political activists, social movements also appear to include "engaged observers"—individuals who are attentive to movement writings and activities, and express moral and even financial support for them, but who take no other action. Although activism in a movement may be the best predictor of future political action, engaged observation may be related to other indicators of political socialization, such as a powerful felt impact of the movement and well-developed political attitudes. Evidence to support this notion is drawn from studies of three samples of college-educated white and black women.     

Beyond drug effects and dependent variables: the use of the Poisson-Erlang model to assess the effects of D-amphetamine on information processing

Several studies have shown that d-amphetamine (DAMP) speeds mean reaction time (RT). However, the use of mean RT may obscure important aspects of the drug response. Therefore we applied the Poisson-Erlang (PE) stochastic model of choice reaction time proposed by Pieters (1985) to the RT distribution. This model proposes that the RT distribution is generated by two states: Processing (P) and Distraction (D). RT represents the sum of the time spent in each of these states. P is the time taken to complete a set of cognitive operations which are required to give a correct response. D represents the time taken by all other activities. RTs were collected using a task (SERS) in which stimulus and response complexity each had two levels, easy and hard. Subjects were tested pre- and postdrug. Drug conditions were: placebo, 10 mg d-amphetamine (DAMP), 4 mg of the dopamine agonist, pimozide, and a combination of DAMP and pimozide (COMBO). Parameters of the model were derived using methods described by Pieters. Four measures were analyzed: Processing Time (PT); Mean Time per distraction (XTD); Distraction Rate (DR); and Total Distraction Time per trial (TDT). Mean RT is also presented. Analyses of the effects of task conditions on the parameters of the model were made using the predrug sessions. Mean RT was increased by both stimulus and response complexities as was PT. TDT was increased by the task conditions. The PE measures did not change over days. DAMP speeded mean RT. However, this effect did not interact with the task factors. DAMP speeded processing and reduced distraction. Processing was speeded only in the hard response condition, distraction time was reduced only in the easy response condition. The results indicate that the PE model can be successfully applied to fast RT tasks. More importantly, the parameters of the model revealed important pharmacological effects that were not apparent in mean RT. DAMP speeds cognitive operations related to motor preparation and reduces the effects of distraction. Consistent with past studies there are no indications that DAMP interacted with stimulus processing. The distraction effect appears to be mediated by an increase in the rate of distraction and a decrease in the average time of these distractions.     

How older adults use cognition in sentence-final word recognition

This study examined the effects of executive control and working memory on older adults’ sentence-final word recognition. The question we addressed was the importance of executive functions to this process and how it is modulated by the predictability of the speech material. To this end, we tested 173 neurologically intact adult native English speakers aged 55–84 years. Participants were given a sentence-final word recognition test in which sentential context was manipulated and sentences were presented in different levels of babble, and multiple tests of executive functioning assessing inhibition, shifting, and efficient access to long-term memory, as well as working memory. Using a generalized linear mixed model, we found that better inhibition was associated with higher accuracy in word recognition, while increased age and greater hearing loss were associated with poorer performance. Findings are discussed in the framework of semantic control and are interpreted as supporting a theoretical view of executive control which emphasizes functional diversity among executive components.     

Behavioral contrast and response independent reinforcement

Four pigeons received pre-training that included presentation of the reinforcer independently of behavior and then baseline training on a variable-interval schedule of reinforcement. With the introduction of a multiple schedule, in which the first stimulus was associated with a response contingent and a second stimulus with a response independent, 1-min variable-interval schedule, a reduction in response rate was obtained in the second component, which was not accompanied by a behavioral contrast effect in the first component. A further three pigeons were given the same pre-training and baseline training before the introduction of an otherwise identical multiple schedule, in which no reinforcement occured in the second component. Behavioral contrast was obtained from all three subjects. The results indicated that under conditions of constant reinforcement density a reduction in responding is not a sufficient condition for the occurrence of behavioral contrast.     

Socialization and themes in popular drama: An analysis of the content of child-rearing manuals and Don Juan plays in sixteenth to twentieth centuries

A content analysis is reported of child-rearing manuals published in sixteenth to nineteenth centuries and of the themes of the Don Juan plays in seventeenth to twentieth centuries. The relationship between the content of the manuals and the themes of the plays supports the thesis that child-rearing patterns advocated in one century are reflected in the next in the attitudes expressed in popular cultural activities towards aggression, achievement and sex roles.     

Missed opportunities: Psychological ramifications of counterfactual thought in midlife women

Counterfactual thinking entails the process of imagining alternatives to reality—what might have been. The present study examines the frequency, content, and emotional and cognitive concomitants of counterfactual thinking about past missed opportunities in midlife women. At age 43, nearly two-thirds of the sample of educated adult women reported having missed certain opportunities at some time in their lives. Most of the counterfactual thoughts concerned missed opportunities for greater challenge in work. Emotional distress at age 33 did not predict later counterfactual thought. Instead, counterfactual thinking at age 43 was associated with concurrent emotional distress. However, acknowledging counterfactual thinking about the past was also associated with envisioning ways to change things for the better in the future. This suggests the possibility that the negative appraisal often entailed in counterfactual thinking may be associated with emotional distress in the short run but with motivational benefits in the long run, at least for middle-aged women.
