How personality relates to intelligence test performance: Implications for a theory of intelligence,ageing research and personality assessment

Previously reported findings indicate that variation of EEG evoked potential parameters is strongly related to both personality and intelligence differences (Robinson, 1982a, b). These data and the associated theory imply that personality should relate to intelligence test performance. Results are described in this report which indicate that subtest profiles obtained with the Wechsler Adult Intelligence Scale (WAIS) differ significantly for Ss scoring highest and lowest on the Extraversion (E) scale of the Eysenck Personality Questionnaire (EPQ); introverts tend to do better on the ‘Verbal’ subtests while extraverts tend to do better on the ‘Performance’ measures. Ss with middling scores on the E scale of the EPQ can also be distinguished in terms of specific WAIS profiles. In this case the results define two contrasting groups. Young male Ss with middling E scores tend to have high Psychoticism (P) and low Lie (L) scores on the EPQ as well as having distinctive WAIS profiles characterized by higher scores on subtests normally associated with a ‘Memory’ or ‘Attention-Concentration’ factor. Higher scores were also obtained by this subgroup on the Picture Arrangement and Block Design subtests which were previously shown to load a P + /L ? factor. The converse is true for older female Ss who also have middling E scores. As well as demonstrating a systematic relationship between personality and intelligence test performance these data provide some further support for a model of brain-behaviour relationships proposed by Robinson. Within this theoretical framework a neurophysiologically meaningful explanation can be provided for the three major factors that reliably emerge in factor-analytic studies of the WAIS. From an applied viewpoint, the data indicate that personality differences can be assessed from performance on tests such as the WAIS. On this issue the results are discussed with particular reference to Gittinger's Personality Assessment System. Implications for ageing research are also discussed.     

Facts which Support the Concept of need or Drive

Research investigating the relationship between body-cathexis and self-esteem has frequently dealt with the problem of the use of body-cathexis scores weighted by the S's rating of the personal importance of body aspects. Since the original research in this area, two studies have presented contradictory data testing the hypothesis that the greater the importance of body aspects to the individual, the greater the correlation between self-esteem and body-cathexis. This hypothesis is tested here using several approaches to the question. These data clearly indicate that there is no relationship between Ss' subjectively stated importance of body aspects and statistical importance in the form of correlations between body-cathexis and self-esteem.     

Inspection time and the mental age deviation hypothesis

The ‘g’-loading of the inspection time (IT) measure was tested by applying Spitz's mental age (MA) deviation model to a sample of non-retarded adolescents and children. An MA 8 and MA 11 group, each composed of below-average, average and above-average intelligence Ss, were compared on an IT task in which latency of responses was also recorded. Results showed that IT related to MA but not to IQ. By contrast, the latency of responding in the IT differentiated Ss by IQ, but not MA, with above-average IQ Ss exhibiting longer response latencies. It was concluded that response latency exhibited a higher ‘g’-loading than did IT.     

AN APPOINTMENT-KEEPING IMPROVEMENT PACKAGE FOR OUTPATIENT PEDIATRICS: SYSTEMATIC REPLICATION AND COMPONENT ANALYSIS

Child health-care appointments that are not kept are an important pediatric problem. Previous research has shown that reducing effort (with a parking pass) and reminding patients (with mailed and telephone reminders) significantly improved appointment keeping for first-time and patient-scheduled appointments. This study, using a posttest-only group design, evaluated the effects of various combinations of that intervention applied to clinic-scheduled follow-up appointments. All combinations of the intervention significantly increased cancellations, but none increased appointments kept or decreased appointments not kept significantly. Log linear analyses showed that the lag time between scheduling and the appointment significantly influenced appointment keeping. The results suggest that if clinics want to increase cancellations, a mailed reminder and effort reduction are sufficient. To increase appointment keeping, other interventions, such as reduced lag time, may be necessary.     

Competing tasks as an index of intelligence

Most studies involving competing (or dual) tasks have been concerned with the investigation of models of attention and have stressed the importance of task characteristics in determining competing-task performance. The relatively few studies which have looked at individual differences in competing-task performance suggest that measures of this performance could reflect operations which are central to cognitive functioning. This paper examines two key questions which stem from this research: is there a separate ability involved in competing-task performance? Is competing-task performance more indicative of general intellectual functioning?A battery composed of both single and competing tasks was presented to 91 Ss. Two sets of scores, ‘primary’ and ‘secondary’, were obtained from the competing tasks. The results indicate that ‘single’ and ‘primary’ scores are basically measuring the same thing but that ‘secondary’ scores measure what is perhaps a time-sharing factor. There is also some evidence that primary and secondary scores are more indicative of the general factor, as measured by this battery, than their single counterparts.     

Effect of Daylight Saving Time on Punctuality for Medical Appointments

We studied the effect of the switch from daylight saving time to winter time on punctuality for medical appointments, thus allowing us to investigate the role of dynamic and analytic modes of time management in time‐based prospective memory tasks. Insofar as some authors assume that the dynamic mode of time management is based on rhythms, we hypothesised that the switch from daylight saving time would cause more disturbances when participants' everyday activity had a weak temporal structure. Results showed that after the switch, participants arrived early for their appointments, but this earliness was not higher for participants whose everyday activity had a low temporal structure than for participants with highly structured everyday activity. Nevertheless, compared to the time they planned to arrive, participants with low regularity of activity arrived earlier after the switch, suggesting that their temporal reference would the time fixed by themselves, rather than the appointment time.

Counseling dropout relative to client attractiveness,disturbance, and expected number of sessions

Participants were 12 counseling center psychologist and thir 257 college-student clients. Immediately after intake, clients indicated whether or not they would make an additional appointment, their reasons for not making another appointment, and the estimated number of sessions they would attend. Counselors rated clients' attractiveness and disturbance and estimated the number of sessions they would have with each client. Clients who did not make a second appointment were generally satisfied with the help they received in one session. Client estimates were more predictive than counselor estimates of actual number of sessions. Relative to less attractive and disturbed clients, more attractive and disturbed clients made and kept post-intake appointments.     

Ageing and perceptual problem-solving: A response analysis approach

This study investigates the nature of age-related changes in performance on a perceptual maze test. A clear linear decline in overall level of performance was found in a cross-sectional study of 20- to 70-yr-old Ss. While some of this decline is due to slowing with age, a detailed analysis of specific components of Ss' response pathways also revealed certain qualitative changes. Although there was no significant evidence of reduced look-ahead or planning in the elderly, there was a clear increase in the proportion of straight-line responses and errors. In contrast to the performance of low-scoring younger Ss, the lower scores of older Ss are not due to their making more errors of all types since they show very selective changes in their response strategies on this task.     

Impact of Appointment Waiting Time on Attendance Rates at a Clinical Cancer Genetics Service

The increase in demand for clinical cancer genetics services has impacted the ability to provide services timeously. Given limited resources, this often results in extended appointment waiting times. Over the last 3 years, the Cancer Genetics Service at the National Cancer Centre Singapore has continued to experience a steady increase in demand for its service. Nevertheless, significant no-show rates have been reported. This study sought to determine whether an association exists between appointment waiting times and attendance rates. Data was gathered for all participants meeting inclusion criteria. Attendance rates and appointment waiting times were calculated. The relationship between mean waiting times for those who did and did not attend their scheduled appointments was evaluated using Welch’s t test and linear regression model. The results showed a significant difference in mean appointment waiting times between patients who did and did not attend (32.66 versus 43.50 days respectively; p?<?0.0001). Furthermore, patients who waited for longer than 37 days were significantly less likely to attend. No-show rates increased as the waiting time increased, at a rate of 19.60% per 20 days and 21.40% per 30 days. In conclusion, appointment waiting time is a significant predictor for patient attendance. Strategies to ensure patients receive an appointment within the necessary timeframe at the desired setting are important to ensure that individuals at increased cancer risk attend their appointments in order to manage their cancer risks effectively.     

Harnessing the power of ‘us’: A randomized wait-list controlled trial of the 5R shared leadership development program (5RS) in basketball teams

High-quality leadership has been established as a key factor driving a team's competitive advantage. Besides the role of the coach, recent research has emphasized the importance of leadership provided by athletes within a team (i.e., athlete leaders). To unlock the potential benefits of athlete leadership, the development of leaders is therefore essential. The 5R Shared Leadership Program (5R^S) aims to identify promising leaders within a team, on different athlete leadership roles, both on and off the field. After the appointment of the leaders, their identity leadership skills to build and strengthen a sense of ‘we’ and ‘us’ are further developed. The design of the present research consisted of a randomized wait-list controlled trial to test the effectiveness of a train-the-trainer approach to develop shared leadership within teams (i.e., 5R^S). We tracked 16 competitive basketball teams throughout a competitive season. While eight teams (four female and four male teams) received 5R^S during the first half of the season (i.e., experimental condition), the other eight teams received 5R^S during the second half of the season (i.e., wait-list control condition). Our findings highlight 5R^S's capacity to develop athlete leaders' ability to create a shared sense of ‘us’, build a stronger team identification, enhance the available social support in the team, help players to remain motivated and confident in their team's abilities, and nurture players' health. Moreover, 5R^S appeared to achieve this impact by using a train-the-trainer approach, regardless of whether the intervention was delivered during the first or second half of the season, and with generally consistent findings amongst male and female teams. The present study both advances the current field on in-group leadership development, and provides practitioners with guidance on how and when to apply 5R^S with the aim of improving team functioning and athletes' health.     

Construct accessibility,depression and the emotional stroop task: Transient mood or stable structure?

Forty-two women who had volunteered for a project on ‘worrying’ were allocated to a ‘high’ or ‘low’ depressed group on the basis of their scores on the Beck Depression Inventory (short-form). High depression was associated with interferences in colour naming of negative compared to neutral words in an emotional Stroop Task, but this effect was more clearly marked when Ss were allocated to groups on the basis of depression levels ascertained 12 months previously. The results strengthen claims made by Gotlib and McCann (1984) that interference in colour naming of negative material reflects stable biases in construct accessibility in depression-prone individuals rather than transient mood disturbance.     

Responding time: A response equivalent to inspection time

A response equivalent to ‘inspection time’ (IT) was developed using a reaction time task in which Ss were required to respond as quickly and accurately as possible to whichever one of two lights appeared on each of a number of trials. The appearance of the lights was followed on all trials by a backward mask. IT was estimated for each S as the shortest duration between the onsets of the light and the backward mask at which the S could respond accurately on virtually every trial. An estimate of ‘responding time’ was then made by setting the duration between the stimulus onset and the mask to each S's individual IT and gradually reducing the time between trials so that Ss had less and less time in which to respond correctly. Responding time was taken to be the shortest such interval at which the S could respond accurately on virtually every trial. This measure was found to be reliable although quantitatively different estimates were obtained using two different methods of presenting the stimulus trials. Responding time was longer for a group of lower-intelligence Ss than for a group of higher-intelligence Ss and the measure was also found to correlate with measured intelligence in the former group. However, it did not itself correlate significantly with IT suggesting that responding time and IT may be measuring different underlying processes.     

Effects of repeated exposure to sexually violent or nonviolent stimuli on sexual arousal to rape and nonrape depictions

The major purpose of this investigation was to examine the effects of repeated exposure to sexually violent stimuli (SVS) in relatively ‘naturalistic settings’ on sexual arousal to rape and nonrape stimuli. Repeated exposure effects using nonviolent erotica were also examined. Sixty-nine male Ss participated in the study. A preexposure session was conducted in which Ss were exposed to written and pictorial depictions of rape and mutually-consenting intercourse. Based on Ss' penile tumescence to these depictions, they were classified as either Force-oriented, Nonforce-oriented or Unclassifiable. Subsequently, Ss were randomly assigned to sexually violent (SVS), sexually nonviolent (SNVS) or control conditions within each force-orientation group. Those assigned to the SVS condition were then exposed to 10 SVS including feature-length films and written and pictorial depictions over a period of 4 weeks. Ss in the SNVS condition were exposed to 10 similar media presentations depicting sexually nonviolent activities only. Ss in the control condition were not exposed to any stimuli during this 4-week period. Soon after completion of the exposure phase, Ss returned for a postexposure laboratory session in which they were presented with four depictions that were similar in theme to those in the preexposure session. Penile tumescence scores and self-reports of sexual arousal were obtained. Results revealed that, for Force-oriented Ss, those exposed to either SVS or SNVS were less aroused to the rape depictions in the postexposure session than those in the control condition. A similar pattern occurred with the nonrape depictions for these Ss, though it was considerably less pronounced. No evidence of a similar ‘satiation’ pattern was obtained for either Nonforce-oriented or Unclassifiable Ss, with these Ss showing no significant differences among the three exposure conditions. The findings are discussed in the context of cognitions, personality differences, conditioning processes, stimulus parameters and response habituation theories. Social and clinical implications are also discussed.     

The Validity of the SHL Customer Service Questionnaire (CSQ)

This study set out to validate the Saville and Holdsworth (SHL) Customer Services Questionnaire (CSQ) by relating test scores to ‘objective measures’ like absenteeism, punctuality, and letters of compliment and complaint, as well as subjective supervisor rating measures. Over 170 airport staff served as subjects. The dependent measures were logically related one to another and there were a few sex and rank differences on them. A number of significant correlations between CSQ subscales and the dependent measures showed two subscales (TC4) Approach to Organizing and (EC2) Need for Results the best correlates of the dependent variable. Of the subscales scores within the three factor scores Relations with People showed fewest significant correlations, and Emotions and Energy most. Results were discussed in terms of the limited research in this field.     

The experience of road environments under two lighting and traffic conditions: Application of a road environment construct list

The aim of this study is to find out whether the different accident rates on two roads may be explained by drivers' different appreciations of these roads. Therefore a rating scale specially developed for the evaluation of drivers' experience of the road environment was used. The study is based on the assumption that experience of the road environment is an important factor in driving behaviour. An experiment was carried out in which two roads were compared in daylight and darkness, with and without traffic. The roads were presented on films. Subjects' evaluation scores appeared to be founded on three factors, which explained 66.8 per cent of the variance. The factors were named ‘hedonic value’, ‘activational value’ and ‘perceptual variation’. Composite scores were constructed from the rating scale scores for each factor, per road, and condition. This revealed that the two roads differed on all three factors. Ambient lighting and traffic conditions also influenced the values of the factors and some interactions were found. The range of scores for one road was greater than for the other. The road that ranked lowest on activational level and perceptual variation, especially during daylight conditions with no traffic, was ranked highest on hedonic value. This combination of conditions and experiences could explain the higher rate of ‘incomprehensible’ single vehicle accidents on that road compared with the other.     

A study of personality variation in women before and after menstruation

The present study was conducted to investigate variations in the personality of women during their premenstrual and postmenstrual periods. PEN and TMAS tests were administered to 25 women (16 unmarried and 9 married) in the age range of 20–30 yr. The study was conducted in two phases, premenstrual and postmenstrual, on the same Ss. The ‘t’-ratios for correlated means were computed to study the differences in personality in the two phases. The results revealed significant differences between premenstrual and postmenstrual P, N and Anxiety scores. The scores on these personality dimensions increased significantly during the premenstrual period.     

Explicit or implicit situation awareness? Measuring the situation awareness of train traffic controllers

Previous research on situation awareness (SA) predominantly focused on its explicit, reasoned, conscious features rather than on the implicit, intuitive, unconscious aspects that are often identified with expert operators. This research investigated implicit levels of SA of train traffic controllers (TTCs) in order to contribute to the body of knowledge on rail human factors research and SA. A novel approach was used to uncover levels of implicit SA through a set of three analyses: (1) fairly low SAGAT values with correlations between SAGAT scores and multiple performance indicators; (2) negative correlations between work experience and SAGAT scores; and (3) structurally lower level-1 SA (perception) scores in comparison to level-2 SA (comprehension) scores in accordance with Endsley’s three-level model. Two studies were conducted: A pilot study – which focused on SA measurements with TTCs in a monitoring mode (N = 9) – and the main study, which involved TTCs from another control center (N = 20) and three different disrupted conditions. In the pilot study, SA was measured through the situation-awareness global assessment technique (SAGAT), perceived SA and observed SA, and performance was measured through punctuality and unplanned stops of trains before red signals. In the main study, SA was measured through SAGAT, and perceived SA and multiple performance indicators, such as arrival and departure punctuality and platform consistency, were assessed. In both studies, the set of three analyses showed consistent and persistent indications of the presence of implicit SA. Endsley’s three-level model and related SAGAT method can be constrained by the presence of these intuitive, unconscious processes and inconsistent findings on correlations between SAGAT scores and performance. These findings provide insights into the SA of TTCs in the Netherlands and can support the development of training programs and/or the design of a new traffic management system.     

IMPROVING PEDIATRIC APPOINTMENT KEEPING WITH REMINDERS AND REDUCED RESPONSE REQUIREMENT

We evaluated the effectiveness of appointment reminders and a reduced response requirement for improving appointment keeping in a hospital ambulatory pediatric clinic. Participants received mailed and telephoned reminders along with a parking pass that reduced the time and effort required to attend the clinic. A multiple baseline analysis of 5,261 appointments over one fiscal year showed that the intervention increased the percentage of appointments kept and decreased the percentage of appointments broken in the continuity clinics of five pediatric health care providers. Social validation, consumer satisfaction, and cost-effectiveness measures, as well as an interrupted time-series analysis, all support the effectiveness of the intervention.     

Changes in Experimental Hypotheses as Determinants of Experimental Results

Two experiments are reported in which changes in Es' (N = 11) experimental hypotheses led to changes in the data they obtained from their Ss-(N = 87). Monitoring of Es' experimental procedure sometimes led to an increase, sometimes to a decrease in the effects of Es' expectancies. For both experiments male. Es significantly exerted the expected biasing effects upon both their male and female Ss. Female Es similarly influenced their female Ss but obtained data from their male Ss significantly opposite to the direction of their hypotheses.
