Adaptable Robots

In this essay we consider some of the characteristics of adaptive biological systems and how these might work as models in designing a robot intended for the exploration of complex environments. Trying to design a robot that has such properties forces one to think hard about the nature of those properties. Here we have one intersection between philosophy and computing. We consider the nature of adaptability and some properties of complex biological systems that are relevant to designing adaptive robots, including direct perception, animacy, affordances, redundant degress of freedom, collective decisions, and emergent properties. We explain how these concepts were used in the development of a robotic arm.     

Evolutionary Psychology: The Wheat and the Chaff

Evolutionary approaches are on the rise in the social sciences and have the potential to bring an all–encompassing conceptual framework to the study of human behavior. Together with neuroscience, which is digging the grave of mind–body dualism, evolutionary psychology is bound to undermine the still reigning human–animal dualism. If a Darwinian reshaping of the social sciences seems inevitable, even desirable, this should not be looked at as a hostile takeover. The underlying theme of this essay is that it is time for psychologists to join the Darwinian revolution, yet the essay also critically reviews current evolutionary psychology. It questions the loose application of adaptationist thinking and the fragmentation of the genome, behavior, and the brain. From biology we learn that not every species–typical trait is necessarily advantageous, and from neuroscience we learn that not every psychological ability or tendency necessarily needs to have its own specialized brain circuitry. But even if the concept of adaptation is hard to apply, psychologists would do well to start looking at human behavior in the light of evolution.     

Using Mnemonics to Increase Early Literacy Skills in Urban Kindergarten Students

The purpose of this study was to examine the effects of an integrated mnemonics strategy on consonant letter naming and consonant sound production on three kindergarten students at-risk for academic failure. Flashcards were developed where the target capital letter was enhanced and imbedded as part of the known picture (e.g., the letter D as the doorknob on a door, the letter F as the flag and flagpole). The mnemonic strategy was assessed using a multiple baseline across students design. Results showed that all three students increased in both the number of consonants named and the number of consonant sounds produced. In addition, all three students maintained performance at the 1 and 3 week followup. Also, based on a pre- and post-assessment, 2 students demonstrated generalization to the ability to name words beginning with consonants letter-sound learned.     

Left to right: representational biases for numbers and the effect of visuomotor adaptation

Adaptation to right-shifting prisms improves left neglect for mental number line bisection. This study examined whether adaptation affects the mental number line in normal participants. Thirty-six participants completed a mental number line task before and after adaptation to either: left-shifting prisms, right-shifting prisms or control spectacles that did not shift the visual scene. Participants viewed number triplets (e.g. 16, 36, 55) and determined whether the numerical distance was greater on the left or right side of the inner number. Participants demonstrated a leftward bias (i.e. overestimated the length occupied by numbers located on the left side of the number line) that was consistent with the effect of pseudoneglect. The leftward bias was corrected by a short period of visuomotor adaptation to left-shifting prisms, but remained unaffected by adaptation to right-shifting prisms and control spectacles. The findings demonstrate that a simple visuomotor task alters the representation of space on the mental number line in normal participants.     

Finite rational self-deceivers

I raise three puzzles concerning self-deception: (i) a conceptual paradox, (ii) a dilemma about how to understand human cognitive evolution, and (iii) a tension between the fact of self-deception and Davidson’s interpretive view. I advance solutions to the first two and lay a groundwork for addressing the third. The capacity for self-deception, I argue, is a spandrel, in Gould’s and Lewontin’s sense, of other mental traits, i.e., a structural byproduct. The irony is that the mental traits of which self-deception is a spandrel/byproduct are themselves rational.

Activating Basic Category Exemplars in Sentence Contexts: A Dynamical Account

This paper examines the influence of context on the processing of category names embedded in sentences. The investigation focuses on the nature of information available immediately after such a word is heard as well as on the dynamics of adaptation to context. An on-line method (Cross Modal Lexical Priming) was used to trace how this process unfolds in time. We found that the information available immediately after a category word is presented is not altered by the sentence context in which the word is immersed. Rather, the structure of availability of particular exemplars of the category resembles the typicality structure of a conceptual representation. The adaptation to context occurs later (between 300 and 450 ms after the category word) and takes the form of a rapid reorganization of the structure rather than a gradual activation of a contextually relevant exemplar. We claim that such data is best accounted for in a dynamical framework, where a coherent global structure emerges through locally guided self-organization.     

The Influence of Clinical Variables on the Psychological Adaptation of Adolescents after Solid Organ Transplantation

This study assessed the influence of clinical and socio-demographic variables on the psychological adaptation of transplanted adolescents. Twenty-six transplanted adolescents and 25 healthy adolescents, aged 13–17, and their parents participated in the study. The following domains were measured: social competence, emotional/behavioral problems, self-concept, self-esteem and subjective well-being. The findings revealed that transplanted boys presented significantly less social competence (U = 26,000, p < .05) and more externalizing problems (U = 25,000, p < .05), social problems (U = 25,000, p < .05) and attention problems (U = 17,500, p < .01) than healthy boys. In contrast, transplanted girls displayed significantly more internalizing problems (U = 47,000, p < .05) and lower physical self-concept (U = 49,500, p < .05) than healthy girls. Hierarchical regression analysis showed clinical variables, especially waiting-list time, significantly predicted attention problems (β = .364, p < .05) and negative affect (β = .632, p < .05) in transplanted adolescents. Also, male (β = −0.554, p < .01) and younger (β = −0.444, p < .01) transplanted adolescents were at risk for attention problems. Our data suggest the importance of the waiting-list time for transplanted adolescents. Efforts to reduce the pretransplant phase would help adolescents achieve better psychological adaptation at long-term posttransplant.     

儿童经验开放性:城乡差异及其与家庭、班级环境的关系

采用问卷法,以483名小学五、六年级儿童为被试,考察了经验开放性的城乡差异及其与家庭环境、班级环境的关系。结果发现:1)城市儿童经验开放性得分显著高于农村儿童。2)家庭(控制性维度除外)、班级环境与经验开放性存在有显著的相关关系。在控制了学校类型、年级和性别因素的影响后,班级环境、家庭社会经济地位、家庭环境的知识性、独立性对于经验开放性仍具有显著的预测作用。     

Adolescents’ preferences for sexual dimorphism are influenced by relative exposure to male and female faces

Exposure to a particular population of faces can increase ratings of the normality and attractiveness of similar-looking faces. Such exposure can also refine the perceived boundaries of that face population, such that other faces are more readily perceived as dissimilar. We predicted that relatively less exposure to opposite-sex faces, as experienced by children at single-sex compared with mixed-sex schools, would decrease ratings of the attractiveness of sexual dimorphism in opposite-sex faces (that is, boys at single-sex schools would show a decreased preference for feminised faces, and girls at single-sex schools would show a decreased preference for masculinised faces). Consistent with this prediction, girls at single-sex compared with mixed-sex schools demonstrated significantly stronger preferences for facial femininity in both male and female faces. Boys at single-sex compared with mixed-sex schools demonstrated marginally stronger preferences for facial masculinity in male faces, but did not differ in their ratings of female faces. These effects were attenuated among some single-sex school pupils by the presence of adolescent opposite-sex siblings. These data add to the evidence that long-term exposure to a particular face population can influence judgements of other faces, and contribute to our understanding of the factors leading to individual differences in face preferences.
