THE USE OF PROMPTS TO ENHANCE VICARIOUS EFFECTS OF NONVERBAL APPROVAL

The effect of nonverbal teacher approval (physical contact in the form of patting approvingly) delivered to target subjects on the attentive behavior of adjacent peers was examined in a special-education classroom. In a reversal design, two pairs of moderately retarded children were exposed to nonverbal approval, with only one subject in each pair receiving approval. In different phases, nonverbal approval was delivered alone or in conjunction with a verbal prompt directed to the adjacent peer or to the class as a whole. The prompt was designed to make salient the target subject's attentive behavior and the nonverbal reinforcing consequences that followed. Providing contingent nonverbal approval alone consistently altered attentive behavior of the target subjects but did not alter the attentive behavior of adjacent peers. However, accompanying nonverbal approval with a verbal prompt did increase attentive behavior of nonreinforced peers.     

Children's binary prediction of partially learnable sequences followed by an all-correct procedure

Six groups of 20 subjects each were run individually in a binary prediction situation with each alternative occurring equally often. Two age groups were employed; subjects were either in second or sixth grades. For one-third of the subjects at each age level, the events occurred in runs of either two or six; another third observed events which occurred in runs of either five or six; the other subjects received a random sequence of events. All subjects then received an additional 50 trials in which every prediction was correct. The results indicated some sensitivity to run length characteristics. Fewer errors of all types were made in the prediction of 5–6 sequences. The verbal reports and all-correct trial protocols revealed that at least the sixth graders employed some simple run length structure rules, although many instances of runs other than those presented in training occurred, showing much processing error. The results were discussed in terms of a general limited-capacity model of information-processing.     

Perception and immediate recall of normal and “compressed” auditory sequences

For a fixed presentation rate, the ratio of speech-to-pause time was varied in three experiments. Ss recalled seven-digit sequences or monitored for item or order information in addition to recall. Removing 33% of the speech and substituting pause time improved recall accuracy and monitoring reaction times. The data suggest that loss of order information in recall may result from cumulative perceptual delays when adequate pause time is unavailable.     

Some processes in children's comprehension of linguistically and visually depicted relationships

A type of paired-associate task was given to 64 kindergarteners and 64 fifth-graders. In four conditions both linguistic and pictorial stimuli were presented simultaneously. In one condition, both a linguistic and pictorial relationship between two objects was depicted; in a second, only the linguistic aspect of the stimuli depicted a relationship; in the third condition, only the picture was relational; and in the fourth, neither the sentences nor the pictures portrayed a relationship between the objects. The results indicate that a relationship in both modes facilitated recall more than the presentation of a relationship in only one mode. A relationship in either mode enhanced recall more than no relationship at all. There were general significant age and IQ effects. The results are interpreted as favoring a duo-system model, with both representation and comprehension occurring within the context of relatively independent systems.     

An automated swim alley for small animals: II. Training and procedures

Experiments were conducted to establish training procedures and testing conditions that produce uniform and reliable swimming performance of rats in an automated swim alley. Data are given on the effect of water temperature and of platform rest interval on swimming speeds. In this system, rats will swim intermittently for as long as 24 h for a distance of more than 7 km.     

Understanding attraction in formal mentoring relationships from an affective perspective

Despite the critical role affect can play in mentoring, a type of close relationships in the workplace, affect has not received much attention in existing mentoring research. Drawing upon Byrne's affect-centered model of attraction, we examined the relationships among mentors' moods during their interaction with protégés, mentors' liking of protégés, and mentoring support received by protégés. Moreover, we also examined the moderating effect of protégés' emotional intelligence (EI) on the relationship between mentors' moods and liking. Based on data collected from 237 ongoing formal mentoring dyads, we found that mentors' positive moods were positively related, and negative moods were negatively related, to mentoring support received through mentors' liking. Furthermore, protégés' EI only moderated the positive relationship between mentors' positive moods and liking such that the positive relationship was stronger for protégés low on EI. Theoretical and practical implications of the findings are discussed.     

Traffic Offences: Planned or Habitual? Using the Theory of Planned Behaviour and habit strength to explain frequency and magnitude of speeding and driving under the influence of alcohol

This study addresses the socio‐cognitive determinants of traffic offences, in particular of speeding and drinking and driving. It has two aims: (1) to test the hypothesis of a direct effect of habits on offences (i.e., independent of intentions) by employing a specific measure of habits (i.e., the SRIH) and (2) to analyse the offences by taking account of three distinct parameters: Frequency, usual magnitude (i.e., the most frequent deviation from the law) and maximal magnitude (i.e., the greatest deviation occasionally adopted) in order to represent more accurately the variability of the offending behaviours. A total of 642 drivers replied to a questionnaire. The results corroborate the idea that intention and habit are distinct and direct determinants of offences. The use of the SRIH dismisses the criticisms made with regard to the measure of past behaviour. The distinction between the three behavioural parameters proves to be relevant, as their determinants are not exactly similar. Finally, attitude and subjective norm had direct effects on the maximal magnitude and/or on the frequency of the offence. The discussion concerns the contribution of this study to the analysis of offences as well as its limitations and addresses the theoretical plausibility of the direct effects of attitude and the subjective norm.
