Anxiety and the selective processing of emotional information: mediating roles of awareness, trait and state variables, and personal relevance of stimulus materials.

Previous research has established that anxiety patients demonstrate a cognitive bias that selectively favours the processing of threat related information. The current experiment employs a variant of a well established colour naming paradigm to address three issues concerning the nature of this anxiety linked pattern of selective processing. First, by considering non-clinical subjects and employing an experimental design capable of dissociating the influence of state and trait anxiety, the current study addresses the hypothesis that state anxiety elevations will elicit differential patterns of selectivity in high and low trait anxious subjects. Second, by presenting stimulus materials within or outside awareness, the study addresses the hypothesis that these processing biases occur automatically, without requiring the use of consciously mediated strategies. Third, by including both emotionally valenced stimulus materials which are related to, and which are unrelated to, the particular source of stress experienced by the subjects, the experiment addresses the hypothesis that such anxiety linked processing biases will be restricted to materials falling within the domain of current personal concern. The results of the present study clearly demonstrate that these three issues are not independent. Fundamentally different patterns of anxiety linked selective processing were observed when stimuli were presented outside awareness, permitting only automatic cognitive processing, and when stimuli were presented within awareness, permitting the use of consciously mediated strategies. The relative roles played by state and trait variables, and the degree to which these effects were influenced by the personal relevance of the stimulus materials, differed in each case. The implications of these findings for future research in this field are discussed.     

Worker estimation of ability requirements of their jobs

A modified version of the Minnesota Job Requirements Questionnaire (MJRQ), representing the GATB aptitudes, was used by workers in 11 selected jobs to rate the ability requirements of their jobs. Worker MJRQ ratings were compared with supervisor MJRQ ratings. Modified Occupational Ability Patterns (OAPs) derived from worker ratings were compared with OAPs based on supervisor ratings, OAPs from expert ratings in the DOT, and OAPs from the empirical GATB approach. Reliability of worker MJRQ ratings was comparable to that of supervisor ratings. Comparisons of mean ratings and variability of ratings of workers in a job category with workers in other jobs, and with supervisors rating the same job, showed construct validity for worker MJRQ ratings, as did intercorrelations of the worker ratings. OAPs derived from worker MJRQ ratings compared favorably with OAPs derived from supervisor MJRQ ratings, from the DOT, and from the GATB. Differences among workers on variables such as satisfaction, age and tenure did not significantly affect their MJRQ ratings. Implications of the worker MJRQ ratings are discussed.     

Application of pavlovian concepts to anxiety and forearm blood flow

Forearm blood flow is presented as an objective index of anxiety. The mechanism by which increase in muscle blood flow occurs as part of a co-ordinated response to “fight or flight” in animals and in man is discussed. An increased forearm blood flow may indicate a considerable degree of internal agitation, although a patient may appear outwardly calm, and this is thought to be evidence of schizokinesis. Patients with anxiety often experience panic attacks with considerable physiological arousal and this may lead to one-trial conditioning. Autokinesis may result in the development of further symptoms, and the Effect of Person on the cardiovascular system in animals and man is considered. Conditionability of anxious patients was investigated and the acquisition and extinction rates of conditional eyelid responses were found to be similar in a group of patients with anxiety, a variety of psychoneurotic disorders, and normal controls. The use of forearm blood flow to monitor reduction in anxiety brought about by medication, desensitization and psychotherapy has been found to be a valuable addition to the objective methods of assessment in psychiatry.     

An experimental analysis of linguistic development: the productive use of the plural morpheme

Operant conditioning procedures were used to establish a generative use of the plural morpheme in the speech of a severely retarded girl. During training trials, reinforcement was presented contingent upon correct imitation of singular and plural verbalizations by the experimenter, in response to objects presented to the subject singly and in pairs. A generative productive plural usage resulted, the girl correctly labeling new objects in the singular or plural without further direct training relevant to those objects. After establishing the singular/plural usage, the contingencies were reversed (reinforcement of plural responses to single objects, and vice-versa). This produced a corresponding reversal of response by the child. The original usage was then recovered by returning to the previous contingencies. A second experiment analyzed certain error responses occurring during the first experiment, and further probed the generative nature of the subject's plural usage. It was found that errors were somewhat more likely to occur in the pluralization of words ending in vowels than of words ending in consonants. Furthermore, several words whose plurals had been learned according to the reversed plural rule, when examined later during reinforcement of normal plural usage, were found then to exemplify the normal rule being reinforced, yet without direct training.     

Observations on the behaviour of patients in a state mental hospital and a general hospital psychiatric unit: A comparative study

The study sought to compare the naturally occurring behaviour of psychiatric patients within a traditional mental hospital ward and a general hospital psychiatric unit. Direct behavioural observations were undertaken to determine the pattern of behaviour exhibited by patients, the amount of time spent in interaction, with whom interaction took place and the content of that interaction. Data were reliably collected by trained observers, using a 10 category behaviour scale. Within each setting 10 psychotic patients, matched for age, sex and diagnosis, were the subjects and 30 min of behaviour was recorded for each subject. Observations revealed that patients in the mental hospital exhibited more disturbed behaviour, and spent less time in interaction, than did those in the general hospital unit. However, the amount of time patients spent interacting with staff was comparable in the two settings, despite marked differences in staffing levels. Analysis of the content of interaction that did occur indicated that the manner in which staff responded to patients' behaviour was not consistent with the application of a behavioural engineering approach to the modification of abnormal behaviour. While staff in both settings were indiscriminate in the way in which they responded to appropriate and inappropriate patient behaviour, a rather more punitive style of interaction was observed in the mental hospital environment. It is concluded that, from a behavioural perspective, neither setting achieved an optimum therapeutic environment.     

The rapid-smoking technique: Therapeutic effectiveness

The study examined the effectiveness of the rapid-smoking technique in terms of two measures of outcome—post-treatment abstinence rate and reduction in smoking achieved by non-abstinent subjects. A total of 75 volunteers (40 men and 35 women) participated in treatment and were randomly allocated to one of four conditions—rapid-smoking alone; rapid-smoking and relaxation training; rapid-smoking, relaxation and contingency contracting; or contingent rapid-smoking. No significant differences between treatment conditions were obtained. For the total sample, abstinence was achieved by 64% of the subjects immediately post-treatment but the probability of remaining abstinent 12 months later was only 0.33. Immediately post-treatment the non-abstinent subjects reduced their rate of cigarette consumption to 34.2% (SD = 29.3) of baseline smoking but by 12 months average consumption had increased to 82.4% (SD = 28.3) of baseline. It is concluded that rapid-smoking gives rise to substantial short-term changes in smoking behaviour but these effects are not sustained.     

Individual differences in stress and fatigue in two field studies of driving

This paper reports the findings of two field studies of Australian drivers in which individual differences in stress and fatigue were investigated. In the first study, 58 professional drivers completed measures of mood, fatigue and other subjective stress state measures, before and after performing a prolonged driving trip. The results indicated that the scales were sensitive to increased fatigue following the driving trip, and correlated appropriately with Fatigue Proneness, a driver stress trait. In the second study, 104 non-professional drivers completed identical subjective stress state measures as the professional drivers, before and after performing a driving trip. Drivers completed a measure of driving-related stress traits, the Driver Stress Inventory (DSI), and a measure of coping, the Driving Coping Questionnaire (DCQ). Both measures were predictive of state response to driving, and the association between Fatigue Proneness and post-drive fatigue found in the first study was replicated. Findings from these studies suggest that fatigue and stress reactions to driving are psychometrically distinct, but may have some common antecedents, such as use of emotion-focused coping. The studies confirm the importance of fatigue and stress as potential safety problems, but also highlight the role of individual differences in response to the demands of driving.     

A Voice and So Much More: The Neglect and Representation of Language in Social Psychology

Linguistic diversity is an irreducible characteristic of the world we live in today, yet the study of language remains relatively neglected in mainstream and critical social psychologies alike. In order to argue for a renewed confrontation between language and critical social psychology, this study presents an overview of both the absence of language from mainstream, experimental social psychology and of the emergence, since the 1970s, of the social psychology of language as a distinctive subfield in the discipline. It is argued that although the social psychology of language made the subject perceptible as a speaking and above all accented subject, foregrounding language as an index of class, ethnicity and race, it achieved this perceptibility without challenging the basic ideological coordinates according to which experimental social psychology conceptualises the world and subjects in relation to language. For this reason, the social psychology of language, despite its important contributions, reproduces an essentially national and monolingual imagination of language related phenomena and linguistic subjectivities. The task for a critical social psychology of language, it is argued, is to 'demythologise' and 'disinvent' language and language ideologies in the discipline.
