The importance of home practice for progressive relaxation training

The efficacy of home practice assignments was evaluated as a component of standardized progressive relaxation training. Subjects reporting general anxiety and tension problems were assigned to either a home practice relaxation, no home practice relaxation or wait-list control condition. Treatment was conducted for 10 sessions over a 5-week period. In addition, subjects in both conditions engaged in in-vivo application of their relaxation skills during a final 2-week application period. Group comparisons showed that both progressive relaxation conditions significantly improved on daily self-monitored general anxiety and tension levels relative to the wait-list control condition. Group analyses of percent subject improvements supported the effectiveness of home practice assignments, especially during the application period. No systematic differences between groups, on physiological and self-report variables, were found during several laboratory relaxation evaluation sessions. This study supports the contribution of home practice assignments to progressive relaxation training.     

Apractic agraphia in a patient with normal praxis

Most right-handed crossed aphasics are not apractic. They usually have agraphia characterized by misspellings but retain the ability to write well-formed graphemes. We describe a right-handed patient with a right parietal lesion who was aphasic and not apractic. He was unable to write any formed graphemes despite a relatively preserved ability to spell aloud. We postulate that praxis and writing are dissociated in this patient because the motor engrams for praxis were located in his left hemisphere and the engrams for writing were in his right hemisphere. In addition, he comprehended commands for limb motor activities (praxis) far better than he comprehended other speech. This suggests that in this patient the areas used to comprehend limb motor commands may be anatomically distinct from areas important in comprehending other aspects of speech.     

Deliberate self-harm,clinical history and extreme scoring on the EPQ

Two hundred consecutive admissions to an inpatient psychiatric unit were assessed on the EPQ following recovery from the disturbance for which they were hospitalized. Case-history data was also checked for these patients and extended by using a clinical-history structured interview, also administered within 1 week of discharge. Results showed that for males, high P and high N was associated with a history of deliberate self-harm (DSH) by mutilation. High N was also associated with parental violence. In females, both low E and high N were associated with a history of self-mutilation. High N scores were also more likely to have appeared in court, and high P females were more likely to have a history of bedwetting and of parental violence.None of the associations between extreme scoring on the EPQ and self-mutilation were found for DSH by overdose.     

Developmental differences in reactions to children labeled mentally retarded

In an attempt to examine age-related differences in response to the mental retardation label, 48 4th and 5th graders and 48 11th and 12th graders were told of a child of their own age and sex who was either labeled mentally retarded or unlabeled and who performed either competently or incompetently in giving a report. Incompetent target children were viewed more negatively than competent ones at both grade levels. The mental retardation label had less generalized impacts, leading girls but not boys (a) to cite lack of ability as the reason for a retarded child's failure, and (b) to hold low expectations that retarded targets would hold jobs, marry, or have children. A developmental shift in responses to the label was evident only on a trait perception measure; younger children stigmatized retarded targets, while older children granted special dispensation of a failing retarded child by viewing him or her more positively than a similarly incompetent but unlabeled child. Since only adolescent boys showed special dispensation, even though girls were more generally attentive to the label, both sex and age differences warrant further examination.     

Antecedents of employees' mental health—The role of career and work satisfaction

It was hypothesized that individual and situational variables, as a whole, will show stronger relationships with work-related attitudes than with mental health indices. Work-related attitudes, on the other hand, were expected to contribute more strongly to mental health than the individual and situational variables. Results obtained from two groups of staff professionals and retail store managers, using primarily questionnaire data, supported these hypotheses. Career and work satisfaction emerged as the strongest contributors to mental health. Situational variables such as job characteristics, supervisory style, and pay related more strongly to the attitudinal variables than to mental health. This pattern suggests that career and work satisfaction may serve as intervening variables in the relationship between situational variables and mental health.     

Selective effects of barbiturate and amphetamine on information processing and response execution

In a 3 × 2 × 2 factoral experiment, 12 subjects carried out a choice reaction task with reaction time (RT) and movement time (MT) as response measures.Independent variables were drug treatment (amphetamine, barbiturate, placebo), visual stimulus degradation and S-R compatibility. Visual stimulus degradation and S-R compatibility showed additive effect on the RT, but did not affect the MT. This confirms that stimulus encoding, response selection and response execution represent independent processing stages. The two drugs had selective effects on the RT and the MT. Barbiturate (as compared to placebo) had no effect on the MT, but it lengthened the RT, and this effect was additive with the effects of S-R compatibility but showed an interaction with the effects of stimulus degradation. Amphetamine (as compared to placebo) shortened the MT, but there was no significant main effect of amphetamine on the RT although the interaction with the effect of S— compatibility was significant. These results suggest that barbiturate affects stimulus encoding whereas amphetamine affects response-related processes..     

Return of fear: The role of inhibition

In a previous study investigating the relationship between subjective, physiological and behavioural changes during treatment of specific phobias, a marked between-session increase was found in subjective fear after high, but not after low intensity phobic stimulation although the groups showed similar fear ratings and heart rates immediately after treatment (Grey et al, 1979). It was hypothesized that the high intensity stimulation led to ‘treatment fatigue’; a state of deactivation, the recovery from which led to a return of fear.In this study high intensity in vivo stimulation was used for the treatment of phobic subjects under conditions of distributed and massed practice. No differences emerged between treatment conditions. A small group of Ss with a conspicuously high heart rate (mean level 120 bpm) when rating zero fear, showed a significant increase in fear after one week's interval, although they had shown similar improvement to the Ss during treatment. Subjects in both treatment conditions showed lower heart rate at all post-treatment assessments than pre-treatment. The high initial heart rate Ss continued to have higher heart rate than other Ss throughout the experiment, although they showed a decrease after treatment. It was only these Ss with desynchronously high heart rate, i.e. high heart rate with zero fear ratings, who suffered a return of fear, whereas high heart rate during high fear did not predict either response to treatment or return of fear. A further finding was a lack of correlation between the behavioural and physiological indices of fear, namely, between distance and heart rate at high levels of fear.     

Second-order conditioning with diffuse auditory reinforcers in the pigeon

Pigeon subjects were used in five experiments investigating second-order conditioning with visual second-order and diffuse auditory first-order stimuli. Experiment 1 used a discriminative conditioning procedure to demonstrate reliable and substantial second-order conditioning with these stimuli. In Experiments 2 and 3, extinction of the auditory first-order stimulus after second-order conditioning had little effect upon responding to the second-order stimulus, when compared to a stimulus whose reinforcer was maintained. Experiment 4 compared directly the susceptibility of second-order responding to extinction of the first-order reinforcing stimulus as a function of the modality of that reinforcer. When a visual second-order stimulus was paired with a visual reinforcer, and the response to the latter was extinguished, then second-order responding was greatly reduced relative to control levels. In contrast, when that reinforcer was an auditory stimulus, second-order responding was not affected by the current value of the first-order stimulus after conditioning. Finally, in Experiment 5 the auditory stimulus was established as a reinforcer through discriminative-operant training. Following second-order conditioning, extinction of responding to this stimulus again had little impact upon responding to the second-order stimulus with which it had been paired. These results are discussed in terms of previous work on second-order conditioning with rat and pigeon subjects.     

Further evidence on androgyny and interpersonal flexibility

The component scales from which Bem's index of psychological androgyny is derived are better thought of as measures of dominance and nurturance, rather than “masculinity” and “femininity.” When the Bem scales were administered to 202 male and female college students, along with eight scales that form an interpersonal circumplex, it was once again found that stereotyped, near-stereotyped, and androgynous classifications on the Bem index generalized to sex-role stereotype classifications on other dimensions of interpersonal behavior, as well. Moreover, the Bem index was found to be based on the best available combination of orthogonal interpersonal scales for measuring sex-role stereotypy. In this recent sample of college students, the hypothesis that Bem's index of androgyny reflects the more general construct of interpersonal flexibility was confirmed for both male and female subjects. The recognition that Bem's index of androgyny is specific to the interpersonal domain should encourage others to develop androgyny indices in other domains such as temperatment, interests, and cognitive styles.
