Different Strokes for Different Folks: The Impact of Sex Dissimilarity in the Empowerment–Performance Relationship

Organizations often utilize empowerment as a way to bolster performance. It is largely assumed, however, that its impact in this capacity is equivalent across organizational members. We tested this notion within a sample of 420 employees belonging to 75 teams in a Chinese organization and found that team empowerment related positively to supervisor‐rated in‐role and self‐rated extra‐role performance through its effect on individual psychological empowerment. More important, employee–coworker demographic dissimilarity moderated both stages of this indirect relationship. Specifically, when employee–coworker sex dissimilarity was higher, the following relationships were attenuated: (a) team empowerment–individual empowerment, (b) individual empowerment–in‐role performance, and (c) individual empowerment–extra–role performance. Collectively, the results illustrate that the impact of empowerment is contingent upon demographic dissimilarity.     

Between Races and Generations: Materializing Race and Kinship in Moraga and Irigaray

Juxtaposing Cherríe Moraga's Loving in the War Years and Luce Irigaray's Speculum of the Other Woman, I explore the ways that sex and race intersect to complicate an Irigarayan account of the relations between mother and daughter. Irigaray's work is an effective tool for understanding the disruptive and potentially healing desire between mothers and daughters, but her insistence on sex as primary difference must be challenged in order to acknowledge the intersectionality of sex and race. Working from recent work on the psychoanalysis of race, I argue that whiteness functions as a master signifier in its own right, and as a means of differentiation between the light‐skinned Moraga and her brown‐skinned mother. Irigaray's concept of blood deepens Moraga's account of her healing and subversive return to her mother. The juxtaposition of Moraga, Irigaray, and contemporary psychoanalysis of race can allow for a necessary revision of Irigaray's psychoanalysis that acknowledges the ways in which sexual difference is indexed by race and sheds new light on her account of the mother–daughter relation.     

Morphological constraints in children’s spoken language comprehension: A visual world study of plurals inside compounds in English

Many previous studies have shown that the human language processor is capable of rapidly integrating information from different sources during reading or listening. Yet, little is known about how this ability develops from child to adulthood. To gain insight into how children (in comparison to adults) handle different kinds of linguistic information during on-line language comprehension, the current study investigates a well-known morphological phenomenon that is subject to both structural and semantic constraints, the plurals-in-compounds effect, i.e. the dislike of plural (specifically regular plural) modifiers inside compounds (e.g. rats eater). We examined 96 seven-to-twelve-year-old children and a control group of 32 adults measuring their eye-gaze changes in response to compound-internal plural and singular forms. Our results indicate that children rely more upon structural properties of language (in the present case, morphological cues) early in development and that the ability to efficiently integrate information from multiple sources takes time for children to reach adult-like levels.     

Human preferences are biased towards associative information

There is ample evidence that the brain generates predictions that help interpret sensory input. To build such predictions the brain capitalizes upon learned statistical regularities and associations (e.g., “A” is followed by “B”; “C” appears together with “D”). The centrality of predictions to mental activities gave rise to the hypothesis that associative information with predictive value is perceived as intrinsically valuable. Such value would ensure that this information is proactively searched for, thereby promoting certainty and stability in our environment. We therefore tested here whether, all else being equal, participants would prefer stimuli that contained more rather than less associative information. In Experiments 1 and 2 we used novel, meaningless visual shapes and showed that participants preferred associative shapes over shapes that had not been associated with other shapes during training. In Experiment 3 we used pictures of real-world objects and again demonstrated a preference for stimuli that elicit stronger associations. These results support our proposal that predictive information is affectively tagged, and enhance our understanding of the formation of everyday preferences.     

Post-traumatic stress symptoms in mothers of children with leukaemia undergoing the first 12 months of therapy: Predictive models

The aim of this study consists in the measurement of psychological health and adaptation in mothers of children during the first 12 months of treatment for leukaemia and in the identification of possible early predictors. Ninety-four mothers were followed longitudinally at one week (T1), one month (T2), six months (T3) and 12 months (T4) post-diagnosis. The instruments used were: PTSD symptom checklist, BSI-18, Problem Scale, Ladder of life and an in-depth interview (EFI-C). Couple connectedness, family routine reorganisation, parental communication around the child's illness and trust in the medical care significantly increased from T1 to T4. Two models are proposed concerning possible predictors of mothers’ PTSS at T2 and at T3. Clinical suggestions are proposed on the basis of our empirical findings in order to plan informative, clinical and practical interventions for mothers of children under treatment for leukaemia.     

Concurrent Relations Between Perspective-Taking Skills,Desire Understanding,and Internal-State Vocabulary

Recent studies suggest that there appears to be a similar developmental sequence in the understanding of mental states in both internal-state language and in standard theory-of-mind tasks. These findings suggest possible developmental relations between children's ability to talk and think about the mind. Two experiments investigated the concurrent relations between internal-state vocabulary and theory-of-mind abilities in 30-month-old toddlers. In Experiment 1, children's internal-state language vocabulary was significantly and specifically related to their concurrent understanding of others' visual and emotional perspectives and was less strongly related to desire understanding. Experiment 2 replicated and extended these findings by examining the link between internal-state vocabulary and visual perspective-taking and comprehension of own versus other's desire, controlling for general verbal skills. Children with a more developed internal-state vocabulary performed better on perspective-taking tasks. These findings suggest that labeling and reasoning about mental states are related abilities at the early stages of theory-of-mind development.     

Reputation-like inference in domestic dogs (<Emphasis Type="Italic">Canis familiaris</Emphasis>)

Humans frequently interact with strangers absent prior direct experience with their behavior. Some conjecture that this may have favored evolution of a cognitive system within the hominoid clade or perhaps the primate order to assign reputations based on third-party exchanges. However, non-primate species’ acquisition of skills from experienced individuals, attention to communicative cues, and propensity to infer social rules suggests reputation inference may be more widespread. We utilized dogs’ sensitivity to humans’ social and communicative cues to explore whether dogs evidenced reputation-like inference for strangers through third-party interactions. Results indicated dogs spontaneously show reputation-like inference for strangers from indirect exchanges. Further manipulations revealed that dogs continued to evidence this ability despite reduction of specific components of the observed interactions, including reduction of visual social cues (i.e., face-to-face contact between the participants in the interaction) and the nature of the recipient (i.e., living, animate agent versus living, inanimate self-propelled agent). Dogs also continued to demonstrate reputation-like inference when local enhancement was controlled and in a begging paradigm. However, dogs did not evidence reputation-like inference when the observed interaction was inadvertent.     

Rats’ memory for time and relational responding in the duration-comparison procedure

Rats were trained in a duration-comparison task to press one lever if the comparison duration (c) was 1.2-s shorter than a standard duration (s), and another lever if c was 1.2-s longer than s. The interval between s and c duration was 1 s. The 10 duration pairs used during training controlled for the absolute duration of c and the total duration of an s-c pair. The total duration of an s-c pair was not predictive of the correct response. In Experiment 1, during equal-duration pair test trials, rats increasingly responded long (i.e., c > s) as the s-c delay was lengthened. In Experiment 2, long responding increased as the s-c delay was lengthened, even when the illumination condition during the s-c delay differed from that during the intertrial interval (ITI). In Experiment 3, transfer to novel duration pairs was assessed. Overall accuracy for the novel duration pairs was significantly above chance, but transfer performance was also affected by the absolute value of the novel c durations. This is the first study to demonstrate that rats can acquire relational duration discriminations. As in previous studies with pigeons the evidence was consistent with subjective-shortening of the standard duration and there was also evidence of a reliance on a mixture of absolute and relational strategies in responding.
