Deliberation Versus Intuition: Decomposing the Role of Expertise in Judgment and Decision Making

What produces better judgments: deliberating or relying on intuition? Past research is inconclusive. We focus on the role of expertise to increase understanding of the effects of judgment mode. We propose a framework in which expertise depends on a person's experience with and knowledge about a domain. Individuals who are relatively experienced but have modest knowledge about the subject matter (“intermediates”) are expected to suffer from deliberation and to benefit from a more intuitive approach, because they lack the formal knowledge to understand the reasons underlying their preferences. Individuals who are high (“experts”) or low (“novices”) on both experience and knowledge are expected to do well or poorly, respectively, regardless of decision mode. We tested these predictions in the domain of art. Experiments 1 and 2 showed that intermediates performed better when relying on intuition than after deliberation. Judgments of experts and novices were unaffected. In line with previous research relating processing style to judgment mode, Experiment 3 showed that the effect of processing style (global versus local) on judgment quality is similarly moderated by expertise.

Event components in autobiographical memories

Autobiographical memories contain activity, location, temporal, and participant information (Lancaster & Barsalou, 1997). Our study analysed potential dominance of activity information in autobiographical memories. The results indicated stability in dominance of the activity component, defined as similar occurrence in first and subsequent reports, and a relative absence of the temporal component in these verbal reports. Activity dominance also occurred when activity information from the verbal reports was used as a retrieval cue for a subsequent report. Temporal information demonstrated a greater lack of facilitation as a retrieval cue. These findings can be explained from the perspective of embodied cognition in which underlying perceptual states that contain activity, location, and other participant information are reconstructed during retrieval, whereas temporal information, as a more abstract component, is not.     

Recognizing cognates and interlingual homographs: Effects of code similarity in language-specific and generalized lexical decision

In four experiments, we investigated how cross-linguistic overlap in semantics, orthography, and phonology affects bilingual word recognition in different variants of the lexical decision task. Dutch-English bilinguals performed a language-specific or a generalized lexical decision task including words that are spelled and/or pronounced the same in English and in Dutch and that matched one-language control words from both languages. In Experiments 1 and 3, "false friends" with different meanings in the two languages (e.g., spot) were presented, whereas in Experiments 2 and 4 cognates with the same meanings across languages (e.g., film) were presented. The language-specific Experiments 1 and 2 replicated and qualified an earlier study (Dijkstra, Grainger, & Van Heuven, 1999). In the generalized Experiment 3, participants reacted equally quickly on Dutch-English homographs and Dutch control words, indicating that their response was based primarily on the fastest available orthographic code (i.e., Dutch). In Experiment 4, cognates were recognized faster than English and Dutch controls, suggesting coactivation of the cognates' semantics. The nonword results indicate that the bilingual rejection procedure can, to some extent, be language specific. All results are discussed within the BIA+ (bilingual interactive activation) model for bilingual word recognition.

The beholder's share in the perception of orientation of 2-D shapes

A considerable amount of research demonstrates that people perceive cardinal orientations (horizontal and vertical) more accurately than other orientations; this is termed the oblique effect. We investigated the interaction of this effect with the degree of elongation of the stimulus. Our stimuli were ellipses with a wide range of aspect ratios, varying from a circle (aspect ratio = 1) to a line (aspect ratio = 123.5). The task was to set a probe line in the same orientation as the long axis of the ellipse. In our first experiment, we determined that performance is degraded as the aspect ratio decreases; furthermore, the bias and response variability are linearly related to a transformation of aspect ratio (roundness). We found significant individual differences; the results show high within-subjects correlations and low between-subjects correlations. In our second experiment, we had observers judge the orientation of circles randomly mixed in with ellipses of low aspect ratio. The observers demonstrated intrinsic preferences and generated reproducible distributions of orientation settings with idiosyncratic profiles. These distributions predict the influence on the response to ellipses with an aspect ratio higher than one and can be considered as the beholder's share in the perception of shape orientation.     

Lexical effects in phonemic processing: facilitatory or inhibitory

This article addresses the questions of how and when lexical information influences phoneme identification in a series of phoneme-monitoring experiments in which conflicting predictions of autonomous and interactive models were evaluated. Strong facilitatory lexical effects (reflected by large differences in detection latencies to targets in words and matched nonwords) were found only when targets came after the uniqueness point of the target-bearing word. Furthermore, no evidence was obtained for lexically mediated inhibition on phoneme identification as predicted by the interactive activation model TRACE. These results taken together point to strong limitations in the way in which lexical information can affect the perception of unambiguous speech.     

When does inconsistency hurt? On the relation between phonological consistency effects and the reliability of sublexical units

Phonological consistency describes to what extent a letter string in one word is pronounced equally in other words. Phonological reliability describes to what extent a sublexical unit is usually consistent throughout a language. The relationship between the two concepts was investigated by comparing five sublexical units (onset-consonants, vowel, end-consonants, and the concatenation of the vowel with begin- or end-consonants) in Dutch and English with respect to their reliability and to how their consistency was related to naming errors and latencies. In a regression analysis, naming latencies and errors on genuine Dutch words (consistent) and imported words (inconsistent) were predicted by the phonological consistency of the five units. The same was done for two sets of English naming data. Consistency had a much stronger effect in Dutch than in English naming studies when all five units were considered. The special role of the vowel plus end-consonants, which has been found in English naming data, could not be demonstrated in Dutch. In both languages, the size of consistency effects mirrors the reliability of the five units.     

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.     

Same-gender and cross-gender peer acceptance and peer rejection and their relation to bullying and helping among preadolescents: comparing predictions from gender-homophily and goal-framing approaches

The relation between bullying and helping and same-gender and cross-gender peer acceptance and peer rejection was examined in a sample of preadolescents aged 11 and 12 years (N=1,065). The authors tested predictions from a gender-homophily approach vs. predictions from a goal-framing approach in which acceptance and rejection are seen as being generated by approach and avoidance goals, respectively. For preadolescents, both approaches predicted a central role for gender, but the gender-homophily approach predicted symmetrical effects for acceptance and rejection, whereas the goal-framing approach predicted strong asymmetries. The data supported the goal-framing approach. The most important findings were that for preadolescents, acceptance is much more frequent and much more gendered than rejection; the absolute impact of helping on acceptance is much larger than that of bullying (and vice versa for rejection); for acceptance, there is a prototypicality effect (i.e., boys accept bullying girls better than nonbullying girls, and girls accept helping boys better than nonhelping boys); and for acceptance, there is a cross-gender ignorance effect (i.e., boys ignore helping in girls, and girls ignore bullying in boys).
