Speech perception, lexicality, and reading skill

This study examined the interaction between speech perception and lexical information among a group of 7-year-old children, of which 26 were poor readers and 36 were good readers. The children's performance was examined on tasks assessing reading skill, phonological awareness, pseudoword repetition, and phoneme identification. Although good readers showed clearly defined categorical perception in the phoneme identification task for both the /bif/-/pif/ and the /bis/-/pis/ continua, the category boundary for /bif/-/pif/ was at longer VOTs than the boundary for /bis/-/pis/, which characterizes the classic lexicality effect. Poor readers showed less sharply defined categorical perception on both continua. Although poor readers did not show the classic lexicality effect, lexicality did affect the overall rate with which phonemes were identified as /b/ or /p/ at each VOT. These findings suggest that the lexicon may operate as a compensatory mechanism for resolving ambiguities in speech perception. Furthermore, statistical correction for group differences in phoneme identification made group differences in phoneme deletion disappear, suggesting that deficits in speech perception may play a causal role in the phonological core deficit associated with reading failure.     

“How good are you in math?” The effect of gender stereotypes on students’ recollection of their school marks

Two studies examined the effect of gender stereotypes on students’ recollection of their school marks in stereotypically feminine (arts) and masculine (mathematics) domains. As predicted, the results of Study 1 indicated that the more students believed in gender stereotypes prior to recall, the more they biased their reported marks, compared to their actual marks, in a stereotype-consistent way (female students underestimated their marks in mathematics and male students underestimated their marks in arts). Study 2, in which the salience of gender stereotypes was manipulated prior to recall, yielded similar findings. The recall of school marks was more stereotype-consistent in a condition of high salience than in a condition of low salience of gender stereotypes. The theoretical implications of these results are discussed.     

Experimentally distinguishing elevation from gratitude: Oh,the morality

Elevation has garnered empirical support as the emotional response to witnessing moral beauty. The current studies investigated elevation’s construct validity by experimentally testing whether feelings of elevation are distinct from gratitude, another moral and ‘other-praising’ emotion. Study 1 demonstrated that feelings of elevation are distinct from gratitude, serenity (i.e. a secondary comparison condition), and boredom (i.e. a control condition). Study 2 added a behavioral outcome measure in the form of monetary donations to a moral charity. The third study expanded on Study 2 by randomly assigning participants to an elevation or gratitude mood induction and then randomly assigning them to have the opportunity to donate to either a moral or an amoral charity. Together, these studies support Haidt’s conceptualization of elevation, clarify Algoe and Haidt’s qualitative assessment of the emotional differences between elevation and gratitude, and reveal that elevation results in different behavioral responses than gratitude.     

Are Workplace Friendships a Mixed Blessing? Exploring Tradeoffs of Multiplex Relationships and their Associations with Job Performance

Theory and research note the ubiquity of multiplex workplace friendships—multifaceted relationships that superimpose friendship with work‐focused interactions—but it is unclear how they compel or hinder job performance. In a study of insurance company employees (n = 168), we found that the number of multiplex workplace friendships in one's social network is positively associated with supervisor ratings of job performance. However, we also found that there is a negative indirect effect on job performance through emotional exhaustion, which is offset, in part, through enhanced positive affect. Results of a second study of restaurant and retail sales employees (n = 182) provide greater insight into the positive and negative effects of multiplex workplace friendships. Specifically, these relationships enhanced job performance through trust but detracted from job performance through maintenance difficulty. Collectively, our results illustrate that having a large number of multiplex friendships at work is a mixed blessing. Although the provision and restoration of resources fostered by multiplex relationships benefits employee job performance, these benefits are muted somewhat by the personal resources they deplete.     

On the power of autobiographical memories: from threat and challenge appraisals to actual behaviour

Autobiographical memories are a major feature of mental life in humans. However, research on the influence of autobiographical recall on actual behaviour is scarce. We predicted and found that general memories of failure and specific memories of success resulted in worse performance than general memories of success and specific memories of failure. This performance pattern was mediated by task appraisal, suggesting that autobiographical memories (of failure and success) impact performance by shaping the perception of the upcoming task. Combined with the fact that these effects occurred even when the content of autobiographical memories was unrelated to the upcoming task, the present research represents an important step forward in understanding how autobiographical recall influences actual behaviour.
