When 'knowing how' is not enough

Two cases are described of students with a common presenting problem — an inability to concentrate while studying. The factors contributing to poor concentration are explored. Some conclusions are drawn about the types of counsellor interventions which might be useful when working with such students.     

When statistical evidence is not specific enough

Synthese - Many philosophers have pointed out that statistical evidence, or at least some forms of it, lack desirable epistemic or non-epistemic properties, and that this should make us wary of...     

When parallel processing in visual word recognition is not enough: new evidence from naming

Low-frequency irregular words are named more slowly and are more error prone than low-frequency regular words (the regularity effect). Rastle and Coltheart (1999) reported that this irregularity cost is modulated by the serial position of the irregular grapheme-phoneme correspondence, such that words with early irregularities exhibit a larger cost than words with late ones. They argued that these data implicate rule-based serial processing, and they also reported a successful simulation with a model that has a rule-based serial component—the DRC model of reading aloud (Coltheart, Rastle, Perry, Langdon, & Ziegler, 2001). However, Zorzi (2000) also simulated these data with a model that operates solely in parallel. Furthermore, Kwantes and Mewhort (1999) simulated these data with a serial processing model that has no rules for converting orthography to phonology. The human data reported by Rastle and Coltheart therefore neither require a serial processing account, nor successfully discriminate among a number of computational models of reading aloud. New data are presented wherein an interaction between the effects of regularity and serial position of irregularity is again reported for human readers. The DRC model simulated this interaction; no other implemented computational model does so. The present results are thus consistent with rule-based serial processing in reading aloud.     

Examining the link between institutional and community violence: Toward a new cultural paradigm

New explanations of cultural processes are sought, in part, because existing hypotheses are at odds with new wave contemporary empirical findings. Namely, a growing body of scholarship calls into question the “racial invariance” hypothesis proposed by Sampson and Wilson (1995), particularly as it applies to Latinos. Based on these findings, it stands to reason that culture, in addition to structure, may be a property of communities that helps to explain racial/ethnic involvement in crime. This article explores the link between institutional and community violence, and then compares traditional perspectives on the influence of culture on violence (e.g. Wolfgang and Ferracuti’s subculture of violence) with newer, more dynamic conceptualizations of the cultural influence of violence in both institutional and community settings (e.g. Sampson and Bean’s relational theory of culture). The authors consider how both institutional and community violence may be explained using a new cultural paradigm, which moves beyond traditional views of “culture as values” to a new relational theory of “culture in action”. They present a model for understanding, and researching, culture that is based on the notion that value systems in institutions and neighborhoods influence one another. Offering examples from recent research on prison culture, they examine the key dimensions of this new cultural paradigm, which describes culture as “intersubjective, performative, cognitive, relational, and world-making”. The authors conclude that further examination of the reciprocal relationship between institutional and community culture is needed before we can begin to consider the policy implications of the “culture in action” paradigm.     

When accuracy is not enough: The moderating effect of perceived appraisal use

It is hypothesized that perceived appraisal use in making pay related decisions will moderate the relationship between instrumentality beliefs and appraisal accuracy related variables. Perceived appraisal use was found to moderate the relationship between instrumentality beliefs and perceived appraisal accuracy, supervisor appraisal behavior, and supervisor knowledge of performance.     

When remembering is not enough: reflecting on self-defining memories in late adolescence

This study examined which kinds of self-defining memories show spontaneous references to larger meanings, and listener responses to two kinds of meaning-lessons and insights. Narratives of three self-defining memories and episodes of telling the memories to others were collected from each of 168 late adolescents (M age=19). Narratives were coded for event type (relationship, mortality, achievement, and leisure) and for references to tension and to meaning (lesson or insight). Narratives of memorable episodes of having told the memories to others were coded for listener response (positive or negative). References to meaning emerged in one-fourth of the memory narratives, and meaning was more common for self-defining memory narratives that contained references to tension. Memories that reportedly had not been told to others in the past showed the same proportion of meaning as did memories that had been told to others (23%), with insights more prevalent than lessons. For memories that had been told to others, insights were more likely to be accepted by listeners than lessons. Implications were discussed for understanding the development of meaning in self-defining memories and the collaborative construction of identity.     

When knowledge is not enough: the phenomenon of goal neglect in preschool children

We argue that the concept of goal neglect can be fruitfully applied to understand children's potential problems in experimental tasks and real-world settings. We describe an assessment of goal neglect developed for administration to preschool children and report data on two measures derived from this task alongside the Dimensional Change Card Sort (DCCS) and an opposite color response inhibition task. The propensity to neglect initial task cues was uniquely linked to response inhibition, whereas neglect of a later cue was uniquely linked to the DCCS. Additional evidence suggests that recovery from neglect can occur and shows that goal neglect varies with the cognitive transparency of the signifying cue. Data demonstrate the importance of, and place constraints on, current theories of information regulation and foreground the notion of graded representations in working memory and executive functioning.     

When knowing the name of objects is not enough to categorize them

Two experiments explored 16-month-olds' learning of new nouns, and their use of these nouns to categorize objects. In both experiments, infants were presented with triads of perceptually dissimilar objects, which were given made-up names, two of the objects receiving the same name. Following each training phase, infants were tested on whether: (a) they could use the names to categorize the objects (Experiment 1), or (b) they had actually learned the association between the names and the objects (Experiment 2). Our results show that 16-month-olds can simultaneously learn the name of three objects, but cannot use these newly learned names to categorize the objects in the absence of any other cue to categorization. These results are discussed in light of different hypotheses regarding the way infants come to use names to categorize objects.     

The locus of the frequency effect in picture naming: When recognizing is not enough

The lexical frequency effect in picture naming is generally assumed to constitute a signature of lexical access. Lexical frequency, however, is correlated with other variables, like concept familiarity, that can produce effects similar to those of lexical frequency in picture naming tasks. In this study, a delayed picture naming task was employed to address the hypothesis that the frequency effect in picture naming is due to variables that affect processing in the perceptual and semantic identification stages (i.e., input stages). Despite the fact that all the input processing stages were completed prior to the presentation of the naming cue, a strong frequency effect was still obtained in this task. These results establish that the lexical frequency effect is independent of variables affecting the input stages of picture naming, and, hence, confirm the lexical frequency effect as a signature effect of lexical access.     

When what you know is not enough: expertise and gender dynamics in task groups

This study investigates how the contribution, identification, and consideration of expertise within groups are affected by gender differences. The authors examined the effects of member expertise and gender on others' perceptions of expertise, actual and own perceptions of influence, and group performance on a decision-making task. The authors' findings are consistent with social role theory and expectation states theory. Women were less influential when they possessed expertise, and having expertise decreased how expert others perceived them to be. Conversely, having expertise was relatively positive for men. These differences were reflected in group performance, as groups with a female expert underperformed groups with a male expert. Thus, contrary to common expectations, possessing expertise did not ameliorate the gender effects often seen in workgroups. The findings are discussed in light of their implications for organizational workgroups in which contribution of expertise is critical to group performance.     

When trying is not enough: Emotion regulation and the effort-success gap in bipolar disorder

Bipolar disorder (BD) is presumed to involve difficulties in emotion regulation. Little is known, however, about the specific emotion regulation profile associated with this disorder. The present study examined the use of specific emotion regulation strategies among individuals with BD (n = 37) and healthy controls (n = 38). Participants' spontaneous use of reappraisal and suppression, as well as their associated effort and success at regulating their emotions, was measured in the context of three emotionally evocative films (neutral, happy, sad). Results indicated that the BD participants made greater use of spontaneous suppression and reappraisal across all films compared to the control group. BD participants also reported greater effort, but less success, when spontaneously regulating emotions. These findings suggest that bipolar disorder is associated with less success when regulating emotions despite a widespread engagement of regulatory efforts. Discussion focuses on the disjunction between troubled emotion functioning in bipolar disorder and sustained efforts to modify intense emotions.

When being right is not enough: four-year-olds distinguish knowledgeable informants from merely accurate informants

Recent evidence demonstrates that children are selective in their social learning, preferring to learn from a previously accurate speaker than from a previously inaccurate one. We examined whether children assessing speakers' reliability take into account how speakers achieved their prior accuracy. In Study 1, when faced with two accurate informants, 4- and 5-year-olds (but not 3-year-olds) were more likely to seek novel information from an informant who had previously given the answers unaided than from an informant who had always relied on help from a third party. Similarly, in Study 2, 4-year-olds were more likely to trust the testimony of an unaided informant over the testimony provided by an assisted informant. Our results indicate that when children reach around 4 years of age, their selective trust extends beyond simple generalizations based on informants' past accuracy to a more sophisticated selectivity that distinguishes between truly knowledgeable informants and merely accurate informants who may not be reliable in the long term.     

When one cue is not enough: Combining fast and frugal heuristics with compound cue processing

One-reason decision-making heuristics as proposed by Gigerenzer, Todd, and the ABC Research Group (1999) Gigerenzer, G. and Todd, P. M. 1999. “Fast and frugal heuristics: The adaptive toolbox”. In Simple heuristics that make us smart, Edited by: Gigerenzer, G., Todd, P. M. and the ABC Research Group. 3–34. New York: Oxford University Press.  [Google Scholar] have been shown to perform accurately. However, such strategies cannot deal with compound cues. We propose the Take The Best Configural Cue (TTB-Configural) as a fast and frugal heuristic that processes compound cues. In a series of three experiments, we analysed whether participants used this heuristic when making cue-based inferences on which of two alternatives had a higher criterion value. In two of the experiments, two cues were amalgamated into a valid compound cue by applying the AND or the OR logical rule, respectively. In the third experiment, there was no valid compound cue. Within each experiment, we also manipulated causal mental models through instructions. In the configural causal model, cues were said to act through the same causal mechanism. In the elemental causal model, cues were said to act through different causal mechanisms. In the neutral causal model, the causal mechanism was not specified. When a highly valid compound existed, and participants had a configural causal model, for the majority of them the strategy that could best account for their choices was TTB-Configural. Otherwise, the strategy that best predicted their choices was the Take The Best (TTB) heuristic.

When learning is not enough: A process model of expatriate adjustment as cultural cognitive dissonance reduction

Although considerable organizational research exists on the topic of expatriate adjustment and early departure, little has focused on the actual psychological processes causing change in adjustment outcomes. Specifically, researchers have not focused on cognitive dissonance that arises from adopting or condoning culturally expected behaviors that are inconsistent with the expatriate’s own values or attitudes. We propose that dissonance experiences and the methods used for dissonance reduction influence expatriates’ adjustment outcomes and, in turn, their tendency for early departure. We further specify key situational and individual difference constructs that regulate these causal relationships. Along with a greater understanding of cross-cultural adjustment, the current model suggests new directions for expatriate research and management.
