Career-specific parental behaviors in adolescents’ development

Parents are major partners in helping adolescents prepare for a career choice. Although several studies have examined links between general aspects of the parent-adolescent relationship and adolescents’ career development, little research has addressed the mechanisms involved. This study aimed to validate a three-dimensional instrument for the assessment of parental career-related behaviors and to examine their associations with career exploration and decision-making difficulties. After testing the dimensional structure of the instrument, we examined the relationship between parents’ behaviors and adolescents’ career development by using data from 359 German adolescents who reported the amount of perceived parental career-related behaviors and their career exploration and decision-making difficulties. The results of structural equation modeling confirmed the hypothesized dimensional structure (support, interference, lack of engagement). While parental support associated positively with career exploration, interference and lack of engagement associated with decision-making difficulties. Furthermore, interference and lack of engagement moderated the relationship between support and exploration. Support moderated the association between interference and decision-making difficulties.     

Tasty non-words and neighbours: The cognitive roots of lexical-gustatory synaesthesia

For lexical-gustatory synaesthetes, words trigger automatic, associated food sensations (e.g., for JB, the word slope tastes of over-ripe melon). Our study tests two claims about this unusual condition: that synaesthetic tastes are associated with abstract levels of word representation (concepts/lemmas), and that the first tastes to crystallise in early development are those triggered by food-names (e.g., apple tastes of apple; Simner & Ward, 2006). This concept/lemma-based proposal is difficult to immediately reconcile with the finding that non-words may also generate tastes (Ward, Simner, & Auyeung, 2005), since non-words have no concept/lemma representations. We manipulated the characteristics of non-words to provide three types of evidence that non-word tastes in fact stem from real word neighbours: Non-words with neighbours (e.g., keach) are more likely to generate tastes than those with no neighbours (e.g., vilps); pseudo-homophone non-words that are orthographically close to real words (e.g., peeple) are more likely to generate tastes than those that are more distant (baybee); and finally, the tastes of non-words are less consistent, and less intense, than those of real words. Additionally, we test the hypothesis that synaesthetic tastes develop initially from food-names by showing that non-words are more intensely flavoured if they are homophonic with food-names (e.g., toffie) versus non-foods (e.g., peeple). From this we conclude that synaesthetic tastes develop from food-names, and that tasty non-words do not challenge a concept/lemma-based account of lexical-gustatory synaesthesia.     

Real rules

Wright is correct in surmising that Wittgenstein’s refusal to be drawn into the metaphysical and epistemological questions that his own discussion of rules allegedly raises results from his rejection of the assumptions that pit the Platonist against the communitarian. This paper shows why the entire idea (which continues to dazzle philosophers)—that in speaking a language or in engaging in other normative practices we are operating a calculus according to strict rules—has to be rejected. It results, in part, from the conflation of different understandings of ‘knowing the rules’: one in which rules can be ‘read off’ from the practice by a theorist and those in which expressions of rules are consulted within the course of the practice.     

On the language specificity of basic number processing: transcoding in a language with inversion and its relation to working memory capacity

Transcoding Arabic numbers from and into verbal number words is one of the most basic number processing tasks commonly used to index the verbal representation of numbers. The inversion property, which is an important feature of some number word systems (e.g., German einundzwanzig [one and twenty]), might represent a major difficulty in transcoding and a challenge to current transcoding models. The mastery of inversion, and of transcoding in general, might be related to nonnumerical factors such as working memory resources given that different elements and their sequence need to be memorized and manipulated. In this study, transcoding skills and different working memory components in Austrian (German-speaking) 7-year-olds were assessed. We observed that inversion poses a major problem in transcoding for German-speaking children. In addition, different components of working memory skills were differentially correlated with particular transcoding error types. We discuss how current transcoding models could account for these results and how they might need to be adapted to accommodate inversion properties and their relation to different working memory components.     

Cognitive conflict and inhibition in primed dichotic listening

In previous behavioral studies, a prime syllable was presented just prior to a dichotic syllable pair, with instructions to ignore the prime and report one syllable from the dichotic pair. When the prime matched one of the syllables in the dichotic pair, response selection was biased towards selecting the unprimed target. The suggested mechanism was that the prime was inhibited to reduce conflict between task-irrelevant prime processing and task-relevant dichotic target processing, and a residual effect of the prime inhibition biased the resolution of the conflict between the two targets. The current experiment repeated the primed dichotic listening task in an event-related fMRI setting. The fMRI data showed that when the task-irrelevant prime matched the task-relevant targets, activations in posterior medial frontal cortex (pMFC) and in right inferior frontal gyrus (IFG) increased, which was considered to represent conflict and inhibition, respectively. Further, matching trials where the unprimed target was selected showed activation in right IFG, while matching trials where the primed target was selected showed activations in pMFC and left IFG, indicating the difference between inhibition-biased selection and unbiased selection.     

Age-related increase in top-down activation of visual features

Previous research suggests that, during visual search and discrimination tasks, older adults place greater emphasis than younger adults on top-down attention. This experiment investigated the relative contribution of target activation and distractor inhibition to this age difference. Younger and older adults performed a singleton discrimination task in which either an E or an R target (colour singleton) was present among distractor letters. Relative to a baseline condition in which the colours of the targets and distractors remained constant, an age-related slowing of performance was evident when either the colour of the target or that of the distractors varied across trials. The age-related slowing was more pronounced in response to target colour variation, suggesting that older adults place relatively greater emphasis on the top-down activation of target features.     

Cognitive style and learning: performance of adaptors and innovators in a novel dynamic task

The influence of cognitive style on performance in a novel dynamic task modelled on the task of controlling air traffic was investigated. It was hypothesized that participants who preferred a more adaptive cognitive style would maintain better rule adherence and safe distances between aircraft in a low‐fidelity air traffic control task than those who preferred a more innovative style. Problems were presented to participants using computer‐based scenarios in screening, practice, and experimental trials. Performance was measured by the number of times the participant violated two types of scenario rules. Screening, practice, and experimental performance were analysed separately. Cognitive style had a significant effect on performance only during experimental trials. Performance of individuals who preferred a more adaptive style improved across experimental trials while those preferring a more innovative style did not. Results suggest that the more innovative participants, although perhaps having some initial advantage, may not be able to sustain performance in this type of task.

Weather as Ecological Events

Gibson’s (1979 Gibson, J. J. (1979/1986). The ecological approach to visual perception. New York: Psychology Press. (Original work published 1979) [Google Scholar]/1986) definition of ecological events suggests that they are different types of change. Weather events exemplify all three varieties that Gibson outlined and can: (1) change the layout of surfaces, (2) change the color or texture of surfaces, and (3) change surface existence. Wind can bring temporary and enduring changes at the ground surface. Clouds can affect visual experiences on the ground through the amount and type of sunlight that is available. Precipitation in the form of rain, ice, and snow can create, disrupt, deform, or destroy surfaces at or on the ground. In this way, weather can change both the optical characteristics of surfaces (e. g., texture, reflectivity, transparency) as well as the affordances of the surfaces (e.g., wetting of surfaces reduces contact friction; high winds change the ease of passing through the medium of air, etc.). We present a taxonomy of weather events based on Gibson’s (1979 Gibson, J. J. (1979/1986). The ecological approach to visual perception. New York: Psychology Press. (Original work published 1979) [Google Scholar]/1986 Gibson, J. J. (1979/1986). The ecological approach to visual perception. New York: Psychology Press. (Original work published 1979) [Google Scholar]) classification of terrestrial events and provide some suggestions for future research.
