The role of expectation and memory‐retrieval techniques in the construction of beliefs about past events

This study assessed social factors affecting the elicitation of false reports for events occurring the day after birth. High, medium and low hypnotizable participants (N=170) were randomly assigned to hypnotic, guided imagery (non‐hypnotic), expectancy or control conditions. Participants were led to believe that they had experienced a specific event on the day after birth. Hypnotic and guided imagery participants were age regressed, while participants in the expectancy condition were provided with cues suggesting access to this memory was feasible. Relative to controls, these participants recalled higher levels of day‐after‐birth reports, although age‐regressed participants reported significantly more event specific details than expectancy participants. Furthermore, high and medium hypnotizables were more likely than low hypnotizables to recall events occurring the day after birth. Implications of this study within the therapeutic setting are discussed. Copyright © 2000 John Wiley & Sons, Ltd.     

Ethnoracial comparisons in anxiety and depression outcomes among Native Hawaiian and Pacific Islander college students

We explored differences in distress scores at intake as well as the change in anxiety and depression scores over the course of 12 therapy sessions for Native Hawaiian and Pacific Islander (NHPI) college students. Data were collected from the Center for Collegiate Mental Health (N = 256,242). Results support the notion that NHPI college students experience anxiety and depression in therapy differently from other ethnic groups with moderate-to-large magnitudes of effect.     

Comment on Wagner,Elejabarrieta and Lahnsteiner (1995): From sperm and ovum to gender stereotypes

Wagner, Elejabarrieta and Lahnsteiner (1995) conclude that people use gender-stereotypic attributes and sexual metaphors in describing the sperm and the ovum. The conclusion is criticized on the basis of two arguments: (1) the sperm is, in actuality, more active than the ovum and this difference is reflected in subjects' judgements; (2) in their study, the researchers themselves induced (a) the person metaphor and (b) gender categories. © 1998 John Wiley & Sons, Ltd.     

Interpreting functional analysis results using the real-time recording of independent and dependent variables

An extended series of functional analysis conditions were conducted to assess the operant function of aggressive behaviors emitted by a 33-year-old female with diagnoses of severe mental retardation and organic psychosis. Results from the primary test conditions were fairly undifferentiated, but response rates were elevated in the control condition. Independent-variable integrity data from the control condition indicated that aggressive behaviors were nearly always contiguous with the fixed-time delivery of experimenter attention. These results are discussed in the context of the current control condition functioning as a possible test for escape from social interaction. © 1998 John Wiley & Sons, Ltd.     

Stochastic pairwise comparative judgements and direct ratings of alternatives in the REMBRANDT system

The REMBRANDT system for multicriteria decision analysis consists of both the multiplicative variant of the AHP (which employs a method of pairwise comparative judgements by a decision maker to arrive at final impact scores for the alternatives under consideration) and SMART, the simple multiattribute rating technique (which utilizes direct rating of alternatives to achieve final impact scores). This paper examines the effect of imprecision or uncertainty in the decision maker's pairwise judgements or ratings of alternatives by expressing each pairwise judgement or rating as a probability distribution, and the structure of REMBRANDT's component models is exploited to derive interval judgements or interval ratings of the alternatives’ final impact scores. These interval judgements or interval ratings can be used to determine the probability of rank reversal amongst alternatives, i.e. to assess the stability of the final impact score vector. © 1998 John Wiley & Sons, Ltd.     

Habit,information acquisition,and the process of making travel mode choices

Three studies examined the role of habit on information acquisition concerning travel mode choices. On the basis of Triandis' (1980) model of attitude–behaviour relations it was expected that habit strength attenuates the elaborateness of choice processes. The studies focused on different phases in the choice process, namely the appreciation of situational cues and appreciation of choice option information. In line with expectations, it was found that, compared to weak habit participants, those who had a strong habit towards choosing a particular travel mode acquired less information and gave evidence of less elaborate choice strategies. It was attempted to break effects of habit by manipulating either accountability demands or level of attention. Although accountability demands raised the level of information acquisition, no interactions with habit were found. Enhanced attention to the choice process initially did override habit effects in a series of choice trials. However, in spite of this manipulation, chronic habit effects emerged during later trials. The results demonstrate the profound effects that habit may have on the appreciation of information about choice situations and choice options. ©1997 John Wiley & Sons, Ltd.     

Orderliness as a Major Dimension of Personality: from 3DPT to 4DPT

Based on our previous criticisms of Eysenck's Psychoticism model (Van Kampen, 1993) a (Dutch) questionnaire is presented to measure the personality dimensions S (Insensitivity), E (Extraversion), N (Neuroticism), and G (Orderliness). In this questionnaire, the 4DPT or Four-Dimensional Personality Test, the dimensions S and G take the place of Eysenck's unidimensional P concept. It could be demonstrated that the four factors are highly invariant with respect to several sample parameters, including the measured dimensions themselves. Moreover, the scales for the measurement of these factors are practically uncorrelated and sufficiently reliable (Cronbach's α). The relationship between the 4DPT dimensions and the Big-Five model is examined to test the idea that the factors S, E, N, and G are at least variants of the Big-Five dimensions Agreeableness, Surgency, Emotional Stability, and Conscientiousness. The results, obtained by correlating the 4DPT with both the NEO-PI of Costa and McCrae and a set of unipolar factor markers developed by Goldberg, confirm our expectations. The findings are presented in the context of the present-day discussion between Eysenck and the proponents of the Big-Five model about the nature and number of basic personality factors. Some comments are also made on the possibility of extending the 4DPT with a fifth scale for the measurement of the remaining Big-Five factor, Intellect or Openness to Experience. © 1997 John Wiley & Sons, Ltd.     

Habitual Susceptibility to Misinformation and Individual Differences in Eyewitness Memory

A novel multiple-event, multiple-item procedure was employed to identify individuals who were habitually susceptible to accepting post-event misinformation. Using this procedure, it was found that many people succumbed at least once to the effects of misinformation, given enough opportunities. Moreover, some individuals could be identified who showed a pattern of repeated susceptibility, accepting some misinformation for each of three separate events. Several individual difference measures discriminated between individuals who were habitually susceptible to false post-event information and those who were not; these include empathy, self-reported vividness of visual imagery and a memory accuracy measure. © by John Wiley & Sons, Ltd.
