When Civic Virtue isn’t Seen as Virtuous: The Effect of Gender Stereotyping on Civic Virtue Expectations for Women

We examined the extent to which observers’ expectations of target employees’ civic virtue organizational citizenship behaviors (OCB) are a function of both observer- (gender stereotype activation, threat) and target-related (gender) influences. Consistent with a role congruity perspective, we proposed that civic virtue (constructive involvement in the political governance process of the organization) will be expected to a lesser extent of women, but only when gender stereotypes are activated. We confirm this hypothesis across two studies. In Study 1, based on a sample of 187 U.S. undergraduate students (101 women, 86 men), we show that less civic virtue is expected of women when observers’ gender stereotypes are experimentally activated (vs. the non-activated condition). Using an additional sample of 197 U.S. undergraduate students (Study 2; 118 women, 79 men), we extend our findings by demonstrating that less civic virtue was expected of women in a high (vs. low) threat (manipulated) condition. Findings for men are included for comparative and general informational purposes only. We observed no significant changes in civic virtue expectations for men due to our study manipulations. Our research extends prior studies by showing that expectations for civic virtue are diminished for women, but only when gender stereotypes and threat are activated.     

On the epistemological analysis of modeling and computational error in the mathematical sciences

Interest in the computational aspects of modeling has been steadily growing in philosophy of science. This paper aims to advance the discussion by articulating the way in which modeling and computational errors are related and by explaining the significance of error management strategies for the rational reconstruction of scientific practice. To this end, we first characterize the role and nature of modeling error in relation to a recipe for model construction known as Euler’s recipe. We then describe a general model that allows us to assess the quality of numerical solutions in terms of measures of computational errors that are completely interpretable in terms of modeling error. Finally, we emphasize that this type of error analysis involves forms of perturbation analysis that go beyond the basic model-theoretical and statistical/probabilistic tools typically used to characterize the scientific method; this demands that we revise and complement our reconstructive toolbox in a way that can affect our normative image of science.     

The contextual action relationship between a tool and its action recipient modulates their joint perception

Facilitatory effects have been noted between tools and the objects that they act upon (their “action recipients”) across several paradigms. However, it has not been convincingly established that the motor system is directly involved in the joint visual processing of these object pairings. Here, we used the attentional blink (AB) paradigm to demonstrate privileged access to perceptual awareness for tool–action recipient object pairs and to investigate how motor affordances modulate their joint processing. We demonstrated a reduction in the size of the AB that was greater for congruent tool–action recipient pairings (e.g., hammer–nail) than for incongruent pairings (e.g., scissors–nail). Moreover, the AB was reduced only when action recipients followed their associated tool in the temporal sequence, but not when this order was reversed. Importantly, we also found that the effect was sensitive to manipulations of the motor congruence between the tool and the action recipient. First, we observed a greater reduction in the AB when the tool and action recipient were correctly aligned for action than when the tool was rotated to face away from the action recipient. Second, presenting a different tool as a distractor between the tool and action recipient target objects removed any benefit seen for congruent pairings. This was likely due to interference from the motor properties of the distractor tool that disrupted the motor synergy between the congruent tool and action recipient targets. Overall, these findings demonstrate that the contextual motoric relationship between tools and their action recipients facilitates their visual encoding and access to perceptual awareness.     

Mother–Calf vocal communication in Atlantic walrus: a first field experimental study

In all colonial pinnipeds studied, mother–young vocal recognition exists and allows rapid and reliable meetings in spite of the confusing environment of the breeding colony. The efficiency of this recognition process guarantees pup survival, especially in species where females alternate foraging sea trips and lactation periods on land. The Atlantic Walrus (Odobenus rosmarus rosmarus) is a highly gregarious pinniped with females attending their calves for an extended period of time (2–3 years). Although we expect mother–calf vocal recognition to occur in this species due to the high density of individuals packed in herds, it has never been experimentally demonstrated. Here, we assessed the individual stereotypy of both mother and calf barks recorded in the wild by measuring frequency and temporal acoustic parameters. Both discriminant function and artificial neural network analyses resulted in high correct classification rates, underlying a well-defined individual stereotypy in parameters related to frequency modulation and frequency values. Playback experiments showed that mothers were more responsive to the barks of their own calf than to those of unrelated young. Finally, propagation experiments revealed that barks propagate at greater distances over water surface than over ice, acoustic features such as frequency modulation and frequency spectrum being highly resistant to degradation during propagation. Thus, acoustic analysis and propagation experiments suggest that these frequency parameters might be the key acoustic features involved in the individual identification process. This experimental study clearly demonstrates that Atlantic walrus has developed a highly reliable mother–calf vocal communication allowing such strong social bond.     

The antisocial phenomenon in adolescence: What is literature telling us?

Our paper offers a reflection on the state of the art of antisocial behaviors in adolescence, seeking to review and synthesize relevant conclusions from developmental investigation on this subject. We begin by identifying the peculiarities of the antisocial phenomenon in adolescence, with particular focus on social and family aspects that may influence social behaviors at this stage, as well as on individual variables that undergo considerable development in adolescence and may play an important role in risk behaviors, such as psychosocial competence, personality, self-concept, and intelligence. The general conclusion points out questions that remain unanswered. Therefore, work seeking to address some of those questions is presented.     

Afro-centric religious consultations as treatment for psychotic disorders among day hospital patients in Santiago de Cuba

We investigated the utilisation of Afro-centric religious treatments for psychotic disorders among a sample of Cuban day hospital patients. Most (55%) had used such treatments and this practice was more common among older persons, although unassociated with any particular religious background or racial heritage. Persons who preferred Afro-centric religious practices to medical ones were more likely to be of African descent or to have received an Afro-centric religious ritual bath as treatment. A case is made for destigmatising Afro-centric religious treatments and for exploring treatment approaches that combine both medical and religious practices in order to achieve more holistic care.     

Adult Age Differences in Inhibitory Processes and their Predictive Validity for Fluid Intelligence

ABSTRACT

According to the inhibition-deficit hypothesis age differences in working memory capacity and fluid intelligence have been attributed to a decline in inhibitory efficiency. Conceptualizing inhibition as multifaceted, 88 participants (49 younger and 39 elderly) completed two versions of the negative priming paradigm (identification and localization), and two variants of the directed forgetting paradigm (listwise and itemwise). Two tasks of the Wechsler Intelligence Test with high loadings on general fluid intelligence (Gf) served as validation criteria. Results revealed task-specific and speed-independent inhibitory deficits in the elderly (lower negative priming in both paradigms; more intrusions in the directed forgetting tasks), as well as higher levels of repetition priming. Significant correlations between measures of inhibition and the Wechsler scores were found in both age groups. Results support the view of multiple inhibitory-like capabilities that play a central role in the decline of higher-order cognitive functions in old age.     

The relevance of temporal cues in a fish sound: a first experimental investigation using modified signals in cichlids

Playback experiments have been a useful tool for studying the function of sounds and the relevance of different sound characteristics in signal recognition in many different species of vertebrates. However, successful playback experiments in sound-producing fish remain rare, and few studies have investigated the role of particular sound features in the encoding of information. In this study, we set-up an apparatus in order to test the relevance of acoustic signals in males of the cichlid Metriaclima zebra. We found that territorial males responded more to playbacks by increasing their territorial activity and approaching the loudspeaker during and after playbacks. If sounds are used to indicate the presence of a competitor, we modified two sound characteristics, that is, the pulse period and the number of pulses, in order to investigate whether the observed behavioural response was modulated by the temporal structure of sounds recorded during aggressive interactions. Modified sounds yielded little or no effect on the behavioural response they elicited in territorial males, suggesting a high tolerance for variations in pulse period and number of pulses. The biological function of sounds in M. zebra and the lack of responsiveness to our temporal modifications are discussed.     

Selecting decision strategies: The differential role of affect

This experiment sought to clarify the potential role of emotional feelings in the systematic impact of implicitly processed affective stimuli on mental effort mobilisation. Participants worked on an attention task during which they were primed with suboptimally presented happiness versus sadness expressions. Before the task, half the participants received a cue for the possible affective influence of “flickers” to be presented during the task. This manipulation usually reduces the impact of conscious feelings on resource mobilisation. As anticipated, sadness primes resulted in higher experienced task demand and higher mental effort (stronger cardiac contractility assessed as shortened pre-ejection period) than happiness primes. Most importantly, instead of reducing the prime effects on mental effort, the cue manipulation significantly increased participants’ effort in general, reflecting additional cognitive demand. The results speak against the idea that affect primes influence effort mobilisation by eliciting conscious emotional feelings.     

Regional conferences—A capacity‐building mandate: Report on CRCP2011—Building Bridges and Building a Regional Structure

The Caribbean Regional Conference of Psychology was held in Nassau, The Bahamas, from 15 to 18 November 2011, under the auspices of the International Association of Applied Psychology (IAAP), the International Union of Psychological Science (IUPsyS), and the International Association for Cross‐Cultural Psychology (IACCP). The conference was hosted by the Bahamas Psychological Association, and organized by a committee chaired by Dr Ava Thompson, College of the Bahamas. The CRCP2011 attracted over 400 participants from 37 countries, including 20 nations/territories in the Caribbean. A broad scientific program, organized around six conference themes, addressed strengths and challenges to psychology in the region; the current state of psychological research, assessment, and intervention; historical, cultural, and language influences; and links between Caribbean and global models. Conference outcomes included planning for a series of publications to expand on conference themes and presentations, as well as establishment of a steering group to launch a regional organization to support the science and practice of psychology in the Caribbean.
