Associations between parental educational/occupational levels and cognitive performance in Spanish adolescents: the AVENA study

We examined the associations between parental educational/occupational levels and cognitive performance in Spanish adolescents. Cognitive performance was measured by a validated Scholar Aptitudes test in 2,162 participants. Parental educational and occupational levels were positively associated with all specific cognitive abilities and the overall score (p<001 to .04). The odds ratios of having a high cognitive performance (top quartile) in adolescents with high parental educational level were 1.6 to 1.7 times higher than for those with a low parental educational level. Similarly, the odds ratios were 1.9 to 2.4 times higher for adolescents with high parental occupational level. These findings suggest an association between parental educational/occupational levels and cognitive performance in Spanish adolescents and support the parents' role in the creation of a stimulating intellectual environment.     

Political Tolerance and Religion: An Age-Period-Cohort Analysis, 1984–2014

Using data from the 1984–2014 General Social Survey, we employ cross classified random effects models to examine age-period-cohort changes in political tolerance by religion, incorporating religious belief, belonging, and behavior into the analyses. The results show large cohort and period based changes in political tolerance of the various religious traditions. The results also suggest that the primary driver of changes over time in political tolerance is best attributed to period effects, not cohort replacement, although there is some evidence of a cohort effect among Roman Catholics. Finally, our results demonstrate that aggregate data analyses can lead to noticeably different results and thus can mask substantial differences between groups.     

Innovative behaviour in fish: Atlantic cod can learn to use an external tag to manipulate a self-feeder

This study describes how three individual fish, Atlantic cod (Gadus morhua L.), developed a novel behaviour and learnt to use a dorsally attached external tag to activate a self-feeder. This behaviour was repeated up to several hundred times, and over time these fish fine-tuned the behaviour and made a series of goal-directed coordinated movements needed to attach the feeder’s pull string to the tag and stretch the string until the feeder was activated. These observations demonstrate a capacity in cod to develop a novel behaviour utilizing an attached tag as a tool to achieve a goal. This may be seen as one of the very few observed examples of innovation and tool use in fish.     

Sign- and goal-tracking in Atlantic cod (<Emphasis Type="Italic">Gadus morhua</Emphasis>)

When animals associate a stimulus with food, they may either direct their response towards the stimulus (sign-tracking) or towards the food (goal-tracking). The direction of the conditioned response of cod was investigated to elucidate how cod read cue signals. Groups of cod were conditioned to associate a blinking light (conditioned stimulus, CS) with a food reward (unconditioned stimulus, US), with the CS and the US located at opposite sides of the tank. Two groups were trained in a delay conditioning procedure (CS = 60 s, interstimulus interval = 30 s) and two groups were trained in a trace conditioning procedure (CS = 12 s, trace interval = 20 s). The response pattern was similar for the delay- and trace-conditioned groups. The initial main response at the onset of the CS was approaching the blinking lights, i.e. sign-tracking. In the early trials, the fish did not gather in the feeding area before the arrival of food. In the later trials, the fish first approached the blinking lights, but then moved across the tank and gathered below the feeder before the food arrived, i.e. sign-tracking followed by goal-tracking within each trial. These two responses are interpreted as reflecting two learning systems, i.e. one rapid, reflexive response directed at the signal (sign-tracking) and one slower, more flexible response based on expectations about time and place for arrival of the food (goal-tracking). The ecological significance of these two learning systems in cod is discussed.     

Internet-mediated distance-learning education in China as an alternative to traditional paradigms of market entry

Globalization and technology are two power forces that have shaped trade, investment, industrial development and people in the twentieth and twenty-first centuries. Faced with these forces, universities, on the one hand, internationalized their curriculums, students and faculty and, on the other hand, enhanced their technological base, such as the use of computers, internet infrastructure, and technology-based instructional capabilities. These two efforts have largely been mutually exclusive with little intersection between the two. This article analyzes the cross-over between a university’s potential to internationalize with respect to China, the most populous country with the second largest Purchasing Power Parity Gross Domestic Product (PPP GDP) in the world, and to use its technological capabilities to extend its educational outreach. Indirect presence in the Chinese market through Internet-mediated distance-learning education is thus proposed because of its attractiveness from effectiveness and efficiency perspectives, and because China has experienced an increase in its technological and infrastructural environments that enable this mode of entry. Distance learning education via e-commerce in China can be economically viable, consistently scalable, politically feasible, and expediently realizable.

Catholic Priests and the Political Order: The Political Behavior of Catholic Pastors

A nationwide mail survey of Catholic priests is analyzed with respect to their political behavior in the presidential election of 2000. Priests exhibit a slight tendency to self-identify as political liberals, and a strong tendency to identify with the Democratic Party. Nevertheless, Bill Clinton won a very narrow victory over Bob Dole among priests in 1996, and George W. Bush trounced Al Gore among Catholic clergy in 2000. My analysis suggests that support for Gore was motivated by concern for hunger and poverty among Catholic priests, while support for Bush was driven primarily by priestly opposition to abortion. Political participation among priests was predicted by the importance attached to social justice concerns, and by congruence between the social and economic views of each priest and his congregation.     

Learning in cod (Gadus morhua): long trace interval retention

Basic knowledge about learning capacities and awareness in fish is lacking. In this study we investigated which temporal gaps Atlantic cod could tolerate between two associated events, using an appetitive trace-conditioning paradigm with blinking light as conditioned stimulus (CS) and dry fish food as unconditioned stimulus (US). CS–US presentations were either temporally overlapping (delay conditioning, CS duration 24 s, interstimulus interval 12 s) or separated by 20, 60, or 120 s (trace conditioning, CS duration 12 s) or 2 h (control, CS duration 12 s). The percentage of fish in the feeding area increased strongly during CS presentation in all delay, 20 s, and 60 s trace groups and in one out of two 120 s trace groups, but not in the control groups. In the 20 and 60 s trace procedures, the fish crowded together in the small feeding area during the trace interval, showing strong anticipatory behaviour. In all the conditioned groups, the fish responded to the CS within eight trials, demonstrating rapid learning. At 88 and 70 days after the end of the conditioning experiments, the delay and 20 s trace groups, respectively, were presented the CS six times at 2-h intervals without reward. All groups responded to the light signal, demonstrating memory retention after at least 3 months. This study demonstrates that Atlantic cod has an impressively good ability to associate two time-separated events and long time retention of learnt associations.     

Interpersonally traumatised patients’ view of significant and corrective experiences in the psychotherapeutic relationship

Background: Clinical experience points to the importance of significant experiences in the therapy relationship for patients who have been interpersonally traumatised but the empirical research is limited.

Aim: The aim was to gain increased knowledge about how significant and potentially corrective experiences within the therapeutic relationship were described by patients in trauma-focused therapy and how the participants thought such experiences might have affected the therapeutic work.

Method: Five patients who were, or recently had been, in trauma-focused therapy were interviewed about their experiences of the therapy relationship. Thematic analysis was used to analyse the interviews.

Results: Four themes were identified: ‘Human contact’, ‘Validation’, ‘To face the painful’ and ‘Development of trust’. Positive experiences in the therapeutic relationship were sometimes seen as crucial for the therapeutic work and for patients’ improvement.

Conclusions: Previous findings about the significance of corrective experiences in psychotherapy were confirmed, particularly experiences of the therapist’s accepting stance, personal and human contact and encouragement. The therapist’s ability to evoke trust in the patient and her capacity to help patients to face painful material may be particularly important for traumatised patients.
