Self‐generated variability in object images predicts vocabulary growth

Object names are a major component of early vocabularies and learning object names depends on being able to visually recognize objects in the world. However, the fundamental visual challenge of the moment‐to‐moment variations in object appearances that learners must resolve has received little attention in word learning research. Here we provide the first evidence that image‐level object variability matters and may be the link that connects infant object manipulation to vocabulary development. Using head‐mounted eye tracking, the present study objectively measured individual differences in the moment‐to‐moment variability of visual instances of the same object, from infants’ first‐person views. Infants who generated more variable visual object images through manual object manipulation at 15 months of age experienced greater vocabulary growth over the next six months. Elucidating infants’ everyday visual experiences with objects may constitute a crucial missing link in our understanding of the developmental trajectory of object name learning.     

The dark side of emotional intelligence: the role of gender and the Dark Triad in emotional manipulation at work

Objective : This study investigated people's willingness to emotionally manipulate others maliciously and disingenuously in the workplace. It also examined the role of gender, emotional intelligence, and the Dark Triad traits in this destructive behaviour. Method : A sample of employees (N = 765; 581 females, 184 males) from varying occupations completed measurements of emotional manipulation willingness in the workplace, emotional intelligence, and the Dark Triad. Results : T-tests revealed that females were significantly less likely than males to engage in both malicious and disingenuous emotional manipulation. In bivariate correlations, higher levels of emotional intelligence were associated with disingenuous emotional manipulation in females only. Emotional intelligence was also a significant contributor to disingenuous emotional manipulation in multiple regression analysis, indicating the existence of a “dark side to emotional intelligence” at work. In females, the magnitude of correlations (small to moderate) between the Dark Triad traits and both forms of emotional manipulation were similar. In males, both forms of emotional manipulation most strongly correlated with Machiavellianism, followed by narcissism, then psychopathy. Conclusion : This study is the first to demonstrate that good emotional intelligence skills can facilitate undesirable workplace behaviours. Emotional manipulation is elevated in males with a relentless drive to achieve goals, and in females with broader deceptive tendencies.     

When All Is Revealed: A Dissociation between Evaluative Learning and Contingency Awareness

Three experiments are reported that address the issue of awareness in evaluative learning in two different sensory modalities: visual and haptic. Attempts were made to manipulate the degree of awareness through a reduction technique (by use of a distractor task in Experiments 1 and 2 and by subliminally presenting affective stimuli in Experiment 3) and an induction technique (by unveiling the evaluative learning effect and requiring participants to try to discount the influence of the affective stimuli). The results indicate overall that evaluative learning was successful in the awareness-reduction groups but not in the awareness-induction groups. Moreover, an effect in the opposite direction to that normally observed in evaluative learning emerged in participants aware of the stimulus contingencies. In addition, individual differences in psychological reactance were found to be implicated in the strength and direction of the effect. It is argued that these results pose serious problems for the contention that awareness is necessary for evaluative learning.
