Oblique rotation in correspondence analysis: A step forward in the search for the simplest interpretation

Correspondence analysis (CA) is a popular method that can be used to analyse relationships between categorical variables. It is closely related to several popular multivariate analysis methods such as canonical correlation analysis and principal component analysis. Like principal component analysis, CA solutions can be rotated orthogonally as well as obliquely into a simple structure without affecting the total amount of explained inertia. However, some specific aspects of CA prevent standard rotation procedures from being applied in a straightforward fashion. In particular, the role played by weights assigned to points and dimensions and the duality of CA solutions are unique to CA. For orthogonal simple structure rotation, procedures recently have been proposed. In this paper, we construct oblique rotation methods for CA that take into account these specific difficulties. We illustrate the benefits of our oblique rotation procedure by means of two illustrative examples.     

Fishing for the right words: decision rules for human foraging behavior in internal search tasks

Animals depleting one patch of resources must decide when to leave and switch to a fresh patch. Foraging theory has predicted various decision mechanisms; which is best depends on environmental variation in patch quality. Previously we tested whether these mechanisms underlie human decision making when foraging for external resources; here we test whether humans behave similarly in a cognitive task seeking internally generated solutions. Subjects searched for meaningful words made from random letter sequences, and as their success rate declined, they could opt to switch to a fresh sequence. As in the external foraging context, time since the previous success and the interval preceding it had a major influence on when subjects switched. Subjects also used the commonness of sequence letters as a proximal cue to patch quality that influenced when to switch. Contrary to optimality predictions, switching decisions were independent of whether sequences differed little or widely in quality.

Neuroticism and attachment insecurity as predictors of bereavement outcome

Adult attachment dimensions as well as the personality trait neuroticism have been shown to be related to psychological adjustment after bereavement. No investigations so far have studied the relative contribution of these constructs to grief and depression. In our study of 219 bereaved parents, the two adult attachment dimensions, attachment anxiety and attachment avoidance, were compared to the personality trait neuroticism in predicting psychological adjustment. The attachment dimensions explained a unique part over and above neuroticism, but contrary to expectations, neuroticism explained more variance than attachment dimensions. Implications are discussed.     

No retrieval-induced forgetting using item-specific independent cues: evidence against a general inhibitory account

Retrieval practice with particular items from memory can impair the recall of related items on a later memory test. This retrieval-induced forgetting effect has been ascribed to inhibitory processes (M. C. Anderson & B. A. Spellman, 1995). A critical finding that distinguishes inhibitory from interference explanations is that forgetting is found with independent (or extralist) cues. In 4 experiments, the authors tested whether the forgetting effect is cue-independent. Forgetting was investigated for both studied and unstudied semantically related items. Retrieval-induced forgetting was not found using item-specific independent cues for either studied or unstudied items. However, forgetting was found for both item types when studied categories were used as cues. These results are not in line with a general inhibitory account, because this account predicts retrieval-induced forgetting with independent cues. Interference and context-specific inhibition are discussed as possible explanations for the data.     

In search of the nonconscious sources of goal pursuit: Accessibility and positive affective valence of the goal state

Two experiments tested the hypothesis that the mere priming of the representation of a goal state motivates people to pursue this state to the extent that it is associated with positive affect. In Experiment 1, all participants completed an affective priming task in which the goal concept of “socializing” was primed and tested for positive valence. Subsequently, they were given an instrumental task which provided the opportunity to pursue that state. It was established that participants put more effort in the task to attain the primed goal state when the implicitly assessed affective valence of the state was more positive. Experiment 2 replicated and extended these effects by showing that a stronger association of the goal state with positive affect—as assessed by the EAST—led to more effort to attain the state, but only when “socializing” was primed.     

The role of automaticity in determining the inclination to forgive close others

Hitherto, the literature on forgiveness has almost exclusively focused on the role of deliberative processes (e.g., attribution processes) in determining forgiveness. However, in the present article, we argue that in the context of close relationships, the inclination to forgive can be relatively automatically evoked in response to an offense. Four studies provide evidence relevant to this general hypothesis. Studies 1 and 2 demonstrate that the subliminal presentation of close others (versus non-close others or a control word) induces a relatively strong inclination to forgive various offenses. Study 3 provides insight into the cognitive processes that underlie the closeness-forgiveness link, demonstrating that thinking of (a transgression of) a close other (compared to a non-close other) leads to enhanced accessibility of the construct of forgiveness. Finally, Study 4 demonstrates that forgiving responses toward a close offender are less dependent on cognitive resources than are forgiving responses toward a non-close offender, suggesting that, in close relationships, the inclination to forgive arises in a relatively effortless, habitual manner. Implications for theorizing on how people forgive are being discussed.     

Behavioral cues to others’ motivation and goal pursuits: The perception of effort facilitates goal inference and contagion

Recent research demonstrates that people spontaneously, i.e., without conscious intent, infer and pursue the goals perceived in others’ behavior, a phenomenon termed goal contagion [Aarts, H., Gollwitzer, P., & Hassin, R. R. (2004). Goal contagion: perceiving is for pursuing. Journal of Personality and Social Psychology, 87, 23-27]. Three experiments extend this work by studying the basic role of perceived behavioral effort in goal inference and pursuit. In an adaptation of the Animated Film Technique, participants were exposed to a movie featuring movements of a ball that implied the goal of helping. The amount of effort in pursuing the implied goal was experimentally varied. Results showed that an increase in perceived effort led to stronger inferences of the implied goal, as was established by enhanced accessibility of the goal representation in a word completion and lexical decision task. Furthermore, as a result of these inferences, participants more strongly pursued the inferred goal of helping. Implications for research on goal inferences and pursuit are briefly discussed.     

Differential Prediction of Immigrant Versus Majority Group Training Performance Using Cognitive Ability and Personality Measures

There are very few studies of the differential prediction of work and training performance for immigrant groups in the Netherlands. Scores on the General Aptitude Test Battery, an intelligence test, and the Amsterdamse Biografische Vragenlijst (ABV), a frequently used Dutch personality test, and training data for 78 immigrant and 78 Dutch trainee truck drivers were collected. Lautenschlager and Mendoza’s (1986) method of step-down hierarchical regression analysis was used to check for bias in the prediction of training results. Some predictor-criterion combinations showed differential prediction, especially with less cognitive and less objective criteria. The results with respect to the intelligence test appear to be in line with the findings of the US literature.     

Procedural justice in authority relations: the strength of outcome dependence influences people's reactions to voice

In this article, we study how the strength of outcome dependence, defined as the extent to which people's outcomes depend on authority's decisions, influences their reactions to voice or no-voice procedures. We suggest that in situations where people are strongly outcome dependent they assume that the authority may not consider their views, and therefore voice procedures exert less influence on people's procedure judgments than in situations where they are not strongly outcome dependent. Findings of two experiments corroborate this line of reasoning: In strongly outcome dependent situations, recipients' procedure judgments are influenced less strongly by voice versus no-voice procedures than in moderate or weak outcome dependent situations. Furthermore, these effects were found for both pre-decision voice (Experiment 1) and for post-decision voice (Experiment 2). It is concluded that strong outcome dependence decreases the value-expressive function of voice opportunities. Copyright © 2007 John Wiley & Sons, Ltd.
