Learning from explaining: does it matter if mom is listening?

The goal of the current study was to examine whether explaining to another person improves learning and transfer. In the study, 4- and 5-year-olds (N=54) solved multiple classification problems, received accuracy feedback, and were prompted to explain the correct solutions to their moms, to explain the correct solutions to themselves, or to repeat the solutions. Generating explanations (to selves or moms) improved problem-solving accuracy at posttest, and explaining to mom led to the greatest problem-solving transfer. The study indicates that explanation prompts can facilitate transfer in children as young as 5 years and reveals that it matters if mom is listening.     

The origins of concepts

Certain of our concepts are innate, but many others are learned. Despite the plausibility of this claim, some have argued that the very idea of concept learning is incoherent. I present a conception of learning that sidesteps the arguments against the possibility of concept learning, and sketch several mechanisms that result in the generation of new primitive concepts. Given the rational considerations that motivate their deployment, I argue that these deserve to be called learning mechanisms. I conclude by replying to the objections that these mechanisms cannot produce genuinely new content and cannot be part of genuinely cognitive explanations.

4.5-month-old infants’ learning, retention and use of object boundary information

4.5-month-old infants can use information learned from prior experience with objects to help determine the boundaries of objects in a complex visual scene (Needham, 1998; Needham, Dueker, & Lockhead, 2002). The present studies investigate the effect of delay (between prior experience and test) on infant use of such experiential knowledge. Results indicate that infants can use experience with an object to help them to parse a scene containing that object 24 (Experiment 1). Experiment 2 suggests that after 24 h infants have begun to forget some object attributes, and that this forgetting promotes generalization from one similar object to another. After a 72-h delay, infants did not show any beneficial effect of prior experience with one of the objects in the scene (Experiments 3A and B). However, prior experience with multiple objects, similar to an object in the scene, facilitated infant segregation of the scene 72 h later, suggesting that category information remains available in infant memory longer than experience with a single object. The results are discussed in terms of optimal infant benefit from prior experiences with objects.     

Montserratian mothers’ and English teachers’ perceptions of teaching and learning

After the explosion of a previously dormant volcano in Montserrat (an island in the Caribbean, in the Leeward Islands of the West Indies, overseas territory of the UK) in 1996, about 3000 people emigrated to England. As the children settled into English schools, the pattern of underachievement observed with previous West Indian immigrants started to repeat itself. However, a new fact emerged: Montserratian parents were unhappy with the standards of mathematics and science in English schools, which they considered low. This paper reports a case study of how two Montserratian mothers and their four children perceived English schools. The parents, a Montserratian and an English teacher were interviewed about their views of teaching and learning. The parents were also videotaped while helping their children with homework; the English teacher watched one of these tapes and commented on the session.The interviews and videos were analysed by themes. The interpretation of the themes identified in the interviews was later checked against the events in the homework sessions. Different implicit conceptions of school emerged from the analysis: Montserratian schools appear to fit an ‘interdependent’ style of socialisation whereas English schools fit a more ‘independent’ style. These implicit conceptions of schooling resulted in misunderstandings between teachers and parents, who did not perceive each other as truly helping the children. Differences were also observed in implicit teaching and learning aims. These differences seem to explain the Montserratian parents’ perceptions of a low standard of work being asked of their children in English schools.It is suggested that teachers of immigrant children would find it useful to understand pupils’ and parents’ implicit conceptions of schools when they receive immigrants in their community. Their communication with parents might work better if it fits with the parental expectations and parents have time to learn the ways of schooling in the host country.     

Achievement and avoidance motivational orientations in the domain of mentoring

To extend research on fundamental motivational orientations into a new domain, we explored the achievement (positive) and avoidance (negative) orientations of formal organization-based mentors and protégés as joint predictors of personal learning experienced by both parties. We also examined the extent of mentoring functions provided by mentors as a hypothesized partial mediator. Regression analyses of 8-month data from 61 dyads revealed that mentors’ personal learning was predicted by protégés’ achievement (positive) and avoidance (negative) orientations, whereas protégés’ personal learning was predicted by their own achievement orientation (positive). Although the extent of mentoring functions facilitated personal learning equally among mentors and protégés, it did not function as a mediator. Finally, mentor-protégé congruence on achievement orientation had implications for the personal learning of protégés.     

The role of avoidance of emotional material in the anxiety disorders

Many psychotherapeutic traditions have conceptualized clinical levels of anxiety as resulting from the avoidance of threatening or emotional material. In this paper, we examine behavioral models of avoidance of emotions and emotional material, integrating findings that support established behavioral theories of emotional avoidance and anxiety, and that extend these theories to further explain the intense, intrusive, and interfering nature of clinical anxiety. Research on the suppression and avoidance of emotional material suggests that emotional avoidance and thought suppression may not only hinder the learning process and maintain anxious responding, but may also (a) paradoxically heighten anxious responding to threatening cues and (b) interfere with emotion functionality, thereby further impeding adaptive responding. Findings are discussed in terms of future research and implications for clinical treatment of anxiety disorders.     

Heroic DVD portrayals: What US and Taiwanese adolescents admire and understand

Viewing media aggression can be a risk factor for the long-term well being of viewers, and heroes have been targeted as a major risk factor in this relationship because they commit justified acts of aggression. However, little is known about the specific aspects of heroic conduct that viewers find worthy of emulation. We examined US and Taiwanese adolescents' and college students' identification with, and perceptions of, heroic characters portrayed in a DVD narrative as well as their comprehension of the narrative. Those who thought that certain characters were heroes were more likely to identify with them. However, the qualities that viewers found attractive in heroes were compassion and thinking before using force, not aggression or vengeance. Those who did not understand the program well were more likely to identify with the villain, and they were also more likely to misattribute prosocial qualities to the villain. The results suggest that at least for older viewers, heroic behavior is admired and emulated for prosocial rather than antisocial conduct, and that poor plot-comprehension is one factor that contributes to younger viewers' identification with, and imitation of, antisocial role models.

Fatty acid amide hydrolase (FAAH) knockout mice exhibit enhanced acquisition of an aversive, but not of an appetitive, Barnes maze task

It is well established that genetic deletion or pharmacological inhibition of the CB₁ receptor disrupts extinction learning in aversive conditioning tasks, but not in appetitive tasks. Consistent with these findings is that genetic deletion or pharmacological inhibition of fatty acid amide hydrolase (FAAH), the primary catabolic enzyme of the endogenous cannabinoid anandamide (AEA), accelerates acquisition as well as extinction in aversive conditioning tasks. However, it is unknown whether FAAH blockade will affect acquisition in an appetitive conditioning task. Therefore, in the present study, we assessed FAAH (−/−) and (+/+) mice in appetitive and aversive Barnes maze conditioning procedures. Here we report that FAAH (−/−) mice displayed accelerated acquisition rates in an aversively-motivated, but not in the appetitively-motivated, Barnes maze task. The CB₁ receptor antagonist, rimonabant attenuated enhanced acquisition in the aversive procedure, consistent with the idea that elevated AEA levels mediate this apparent nootropic effect. These findings support the hypothesis that stimulation of the endocannabinoid system enhances learned behavior in aversive, but not appetitive, conditioning paradigms.     

On the Light Doves and Learning on Mistakes

Each type of learning is proposed as being a three-stage process, composed of: (i) recognition of a perceptual situation and performance of an action corresponding thereto; (ii) observation of a deviation of the action result from an expected outcome; (iii) re-arrangement of the conceptual framework of reasoning to meaningfully assimilate the observed deviation. In order to evaluate a general, systemic significance of the concept of learning proposed hereby, the latter is assessed from perspectives that correspond to diverse levels of organizational complexity of Nature. Thermodynamic concepts, constructivist and autopoietic frameworks of analysis of cognitive phenomena, and the aspects of social sciences are intertwined so as to support the all-encompassing meaning of the general pathways of learning proposed herein. Numerous ethical consequences, with a particular emphasis on educational approaches, are derived from accepting such a general nature of learning and development. Naturally implied dialectical form of evolution, according to which prosperous and favorable features of human creativity arise solely from problem-solving situations, is further discussed.
