Linking parents' work pressure and adolescents' well-being: insights into dynamics in dual-earner families

This study focused on the connections between mothers' and fathers' work pressure and the psychological adjustment of their older (M = 15 years) and younger (M = 12.5 years) adolescent offspring in a sample of 190 dual-earner families. Structural equation models revealed that the effects of work pressure on adolescent well-being were mediated by parental role overload and parent-adolescent conflict. Work-family linkages were similar for mothers and fathers with one exception: Fathers' work pressure predicted both parents' feelings of role overload, whereas mothers' work pressure predicted only their own overload, not their spouses'. The patterns of association were consistent for older and younger adolescent siblings.     

Investigating behavior inhibition in obsessive-compulsive disorder: Evidence from eye movements

We investigated the role of inhibition failure in Obsessive Compulsive Disorder (OCD) through an eye tracking experiment. Twenty-five subjects with OCD were recruited, as well as 25 with Generalized Anxiety Disorder (GAD) and 25 healthy controls. A 3 (group: OCD group, GAD group and control group) × 2 (target eccentricity: far and near) × 2 (saccade task: prosaccade and antisaccade) mixed design was used, with all participants completing two sets of tasks involving both prosaccade (eye movement towards a target) and antisaccade (eye movement away from a target). The main outcome was the eye movement index, including the saccade latency (the time interval from the onset of the target screen to the first saccade) and the error rate of saccade direction. The antisaccade latency and antisaccade error rates for OCDs were much higher than those for GADs and healthy controls. OCDs had longer latency and error rates for antisaccades than for prosaccades, and for far-eccentricity rather than near-eccentricity stimuli. These results suggest that OCDs experience difficulty with behavior inhibition, and that they have higher visual sensitivity to peripheral stimuli. In particular, they show greatest difficulty in inhibiting behavior directed towards peripheral stimuli.     

Effects of object asymmetry on visual attention

Unilateral neglect has been demonstrated relative to the intrinsic left side of objects, even when presented in the preserved hemispace. These results have been interpreted as evidence of an object-centered reference frame. In the present study, neurologically normal individuals were presented with letter stimuli having distinguishing features to the right (R) or left (J) of their intrinsic midline, shown in normal and mirror parity, and in six angle rotations. RTs confirmed that participants rotated the letters to the upright to decide parity: such rotation would align the object-centered and viewer-centered frames of reference, suggesting that not controlling for mental rotation would confound this effect. In addition, a dot, presented lateral to the main letter stimulus, resulted in quicker parity decisions when on the maximally-informative side of the letter. Together, the results suggest that apparent object-centered neglect may arise from the combined effects of mental rotation and within-object information asymmetries.     

Young children can extend motion verbs to point-light displays

In the first study using point-light displays (lights corresponding to the joints of the human body) to examine children's understanding of verbs, 3-year-olds were tested to see if they could perceive familiar actions that corresponded to motion verbs (e.g., walking). Experiment 1 showed that children could extend familiar motion verbs (e.g., walking and dancing) to videotaped point-light actions shown in the intermodal preferential looking paradigm. Children watched the action that matched the requested verb significantly more than they watched the action that did not match the verb. In Experiment 2, the findings of Experiment 1 were validated by having children spontaneously produce verbs for these actions. The use of point-light displays may illuminate the factors that contribute to verb learning.     

Decoding human brain activity during real-world experiences

The human brain evolved to function and survive in a highly stimulating, complex and fast-changing world. Attempting to ascertain the neural substrates of operating in naturalistic contexts represents a huge challenge. Recently, however, researchers have begun to use several innovative analysis methods to interrogate functional magnetic resonance imaging (fMRI) data collected during dynamic naturalistic tasks. Central to these new developments is the inventive approach taken to segregating neural activity linked to specific events within the overall continuous stream of complex stimulation. In this review, we discuss the recent literature, detailing the key studies and their methods. These analytical techniques can be applied in a wide range of cognitive domains and, thus, offer exciting new opportunities for gaining insights into the brain bases of thoughts and behaviours in the real-world setting where they normally occur.     

Deconstructing episodic memory with construction

It has recently been observed that the brain network supporting recall of episodic memories shares much in common with other cognitive functions such as episodic future thinking, navigation and theory of mind. It has been speculated that 'self-projection' is the key common process. However, in this Opinion article, we note that other functions (e.g. imagining fictitious experiences) not explicitly connected to either the self or a subjective sense of time, activate a similar brain network. Hence, we argue that the process of 'scene construction' is better able to account for the commonalities in the brain areas engaged by an extended range of disparate functions. In light of this, we re-evaluate our understanding of episodic memory, the processes underpinning it and other related cognitive functions.     

A reanalysis of the CARIN theory of conceptual combination

The competition among relations in nominals (CARIN) theory of conceptual combination (C. L. Gagné & E. J. Shoben, 1997) proposes that people interpret nominal compounds by selecting a relation from a pool of competing alternatives and that relation availability is influenced by the frequency with which relations have been previously associated with the modifying concept. The current authors derived relation frequencies by using a sample of compounds occurring in the British National Corpus and compared them with those derived by Gagné and Shoben. The authors demonstrated that the original relation frequencies are unrepresentative and that Gagne' and Shoben's technique for dichotomizing them into high and low is unreliable. In addition, the authors revealed anomalies in the mathematical instantiation of the CARIN model and showed that it does not provide evidence for competition among relations.     

Integrating and Enacting ‘Social and Ethical Issues’ in Nanotechnology Practices

The integration of nanotechnology’s ‘social and ethical issues’ (SEI) at the research and development stage is one of the defining features of nanotechnology governance in the United States. Mandated by law, integration extends the field of nanotechnology to include a role for the “social”, the “public” and the social sciences and humanities in research and development (R&D) practices and agendas. Drawing from interviews with scientists, engineers and policymakers who took part in an oral history of the “Future of Nanotechnology” symposium at the Cornell NanoScale Facility, this article examines how nanotechnology’s ‘social and ethical issues’ are brought to life by these practitioners. From our analysis, three modes of enactment emerge: enacting SEI as obligations and problems-to-be-solved, enacting SEI by ‘not doing it’ in the laboratory, and enacting SEI as part of scientific practice. Together they paint a complex picture where SEI are variously defined, made visible or invisible, included and excluded, with participants showing their skill at both boundary-work (Gieryn Am Sociol Rev 48:781–795, 1983, 1999) and at integration. We conclude by reflecting on what this may mean for the design and implementation of SEI integration policies, suggesting that we need to transform SEI from obligations into ‘matters of care’ (Puig de la Bellacasa Soc Stud Sci 41(1):85–106, 2011) that tend to existing relationalities between science and society and implicate practitioners themselves.
