THE EFFECT OF ELICITATION METHODS ON PERSONAL CONSTRUCT DIFFERENTIATION AND VALENCE

The effect of personal construct elicitation methods on construct content and structure was addressed in two studies. In Study 1, a between-subjects design was used to compare Kelly's (1955) original Triadic Difference method of elicitation with a Dyadic Opposite method. Study 2 used a fully-crossed, mixed factorial design to compare Kelly's (1955) Triadic Difference method with Epting, Suchman, and Nickeson's (1971) Triadic Opposite method. Results showed that "difference" methods of construct elicitation produced significantly higher levels of construct differentiation, lower numbers of positive emergent construct poles, and less socially undesirable implicit construct poles than "opposite" methods (see also Caputi & Reddy, in press). Implications of these findings are discussed in relation to a critical reappraisal of repertory grid methods.     

Upon Reflection

I report on the fate of three methodological and metatheoretical ideas introduced by Brunswik roughly half a century ago. All were greeted with more than the usual hostility because they challenged the conventional beliefs of the time. All have survived in unexpected ways. I also address certain sins of commission and omission made during the neo-Brunswikian phase of the development of Social Judgement Theory. My hopes and fears for the future are mentioned     

The Effect of Motor Preparation on Changes in H Reflex Amplitude During the Response Latency of a Warned Reaction Time Task

Monosynaptic Hoffman reflexes (H reflexes) were recorded from the soleus muscle during the response latency of a warned reaction time (RT) task that required plantarflexion of the foot. The task was done under four conditions of predictability of the response signal (RS), created by the factorial combination of foreperiod duration (1 and 4 s) and variability (fixed and variable). RT varied systematically with RS predictability and was facilitated in conditions that favored prediction of the RS. The response latency was divided into two successive phases by the onset of reflex augmentation: a premotor phase of constant reflex amplitude and a succeeding motor phase marked by progressively increasing reflex amplitude. Reflex augmentation during the motor phase was coupled more closely to the imminent movement than to the preceding signal to respond. The duration of the premotor phase was unaffected by RS predictability, but the duration of the motor phase (like RT) was shorter when the RS was more predictable. The maximum H reflex amplitude reached during the motor phase was greater when the RS was more predictable. The tonic level of H reflex amplitude during the premotor phase was greater in conditions that made prediction of the RS difficult. A second experiment showed that this difference was present throughout the foreperiod.

These results suggest that conditions that favor prediction of the RS enhance motor preparation. Changes in motor preparation (which affect RT) affect the processes underlying reflex augmentation in the motor phase. Enhanced preparation may allow more efficient organization of the descending commands to move, causing higher levels of spinal excitability to be reached in a briefer time. The higher tonic reflex amplitudes in the premotor phase and throughout the preceding foreperiod, in conditions that make prediction of the RS difficult, appear to reflect heightened general arousal.     

Performance and Learning of Generalized Motor Programs: Relative (GMP) and Absolute (Parameter) Errors

The effects of practice (Experiment 1) and parameter variability (Experiment 2) on the learning of generalized motor programs (GMPs) and movement parameterization were investigated In each experiment, 2 tasks with different relative force-time structures were tested. Participants (N = 32, Experiment (N = 40, Experiment 2) attempted to exert a pattern of force that resembled in force and time a waveform that was displayed on a computer monitor. In both experiments, the analysis suggested that the GMP, although refined over practice, was relatively stable (i.e., resistant to decay and interference), even early in practice (after 20 trials). In addition, the results indicated that constant and variable parameter practice did not differentially affect GMP learning but did degrade the learning of the parameter that was not varied. The data provided additional evidence for the dissociation of the GMP and the parameterization processes proposed in GMP theory. Contrary to schema theory, the present data suggest an interdependence between the force and the time parameters: The manipulation of 1 of the parameters has a negative effect on the learning of the other parameter.     

Centrality Preferences in Choices Among Similar Options

Three explanations were explored for the finding that people prefer the middle option rather than the extremes when choosing from an array of similar options. In Study 1, 68% chose the middle item from a set of three highlighters and three surveys, whereas 32% chose an item from either end, p < .0001. In Study 2, 71% selected the middle chair from a row of three chairs that were either all empty, or had a backpack occupying either one of the two end chairs, p < .0001. These results support a minimal mental effort principle rather than a preference for symmetry rule. In Study 3, 54.2% recalled more graphic items from the center poster of a 3-poster collage, whereas 31.3% and 14.5% recalled more items from the left and right posters, respectively, p < .004. These findings lend additional support to a focus of attention explanation.     

When relationships do not live up to benevolent ideals: Women's benevolent sexism and sensitivity to relationship problems

Benevolent sexism promises women a revered place within intimate relationships, which should lead to greater dissatisfaction when they face relationship difficulties. We collected self‐reports of relationship problems and relationship satisfaction (Study 1; N = 91 heterosexual couples), relationship problems and relationship evaluations daily over 3 weeks (Study 1), and hurtful partner behaviour and relationship evaluations over 10 days (Study 2; N = 86 women). Women's endorsement of benevolent sexism predicted sharper declines in relationship satisfaction when they faced greater relationship problems (Study 1) and hurtful partner behaviour (Study 2). These effects were magnified in longer relationships (Studies 1 and 2), indicating that the sensitivity to relationship problems associated with women's endorsement of benevolent sexism is particularly pronounced when women have more invested in their relationship role being revered and cherished. The results suggest that women who endorse benevolent sexism are vulnerable within their relationships because their satisfaction is contingent upon the fulfilment of the promises of benevolent sexism.

The diagnosticity of color for emotional objects

Object classification can be facilitated if simple diagnostic features can be used to determine class membership. Previous studies have found that simple shapes may be diagnostic for emotional content and automatically alter the allocation of visual attention. In the present study, we analyzed whether color is diagnostic of emotional content and tested whether emotionally diagnostic hues alter the allocation of visual attention. Reddish-yellow hues are more common in (i.e., diagnostic of) emotional images, particularly images with positive emotional content. An exogenous cueing paradigm was employed to test whether these diagnostic hues orient attention differently from other hues due to the emotional diagnosticity. In two experiments, we found that participants allocated attention differently to diagnostic hues than to non-diagnostic hues, in a pattern indicating a broadening of spatial attention when cued with diagnostic hues. Moreover, the attentional broadening effect was predicted by self-reported measures of affective style, linking the behavioral effect to emotional processes. These results confirm the existence and use of diagnostic features for the rapid detection of emotional content.     

The Effect of Image Features on Judgments of Homophily,Credibility, and Intention to Use as Avatars in Future Interactions

Avatar characteristics influence the perception of the people they represent in a process that is remarkably similar to the way physical bodies influence person perception offline. This is consistent with the Social Responses to Computer Technologies model, which argues that people respond similarly to computers and people as long as sources are perceived to be intelligent. Similarly, Information Processing Theory suggests that the viewers apply the same evaluation sequences to nearly all sources and that more processing resources are allocated to perceiving an entity with social potential. To address the extent to which static avatars are perceived to be intelligent and human like, or have social potential, participants (N = 261) each evaluated a random set of 10 images as potential avatars. The avatars varied with respect to level of computer manipulation, visible indicators of masculinity, and anthropomorphism (having human characteristics). Results confirm that even static avatars are anthropomorphized and that visual characteristics influence perceptions of the avatars. Level of computer manipulation, masculinity, and anthropomorphism all influence perceived levels of realism, competence, and the sense of homophily with the avatar. The implications of these results for theory, future research, and for users and designers of communication systems are discussed.
