Spontaneous individual differences in cognitive performances of young adult rats predict locomotor response to amphetamine

Inter-individual differences in cognitive capacities of young adult rats have largely been ignored. To explore this variability and its neurobiological bases, the relationships between individual differences in working memory and locomotor responses to novelty and to amphetamine were investigated in SD rats. Groups of good and poor learners were isolated, the latter demonstrating a markedly slower learning of the task compared to performant rats, with more perseverations independently to motivational state. They also presented a much higher increase in amphetamine-induced locomotion that remained significant for more than 1h after the injection. These results provide evidence that variability in cognitive capacities can be used to reveal their neurobiological substrates. They open new perspectives to study a possible cognitive origin of addictive behaviors and to investigate the involvement of these inter-individual differences on those observed later in life.     

Interaction and bio-cognitive order

The role of interaction in learning is essential and profound: it must provide the means to solve open problems (those only vaguely specified in advance), but cannot be captured using our familiar formal cognitive tools. This presents an impasse to those confined to present formalisms; but interaction is fundamentally dynamical, not formal, and with its importance thus underlined it invites the development of a distinctively interactivist account of life and mind. This account is provided, from its roots in the interactivist biological constitution of life, through the evolution of the dual internal regulatory capacities expressed as intentionality and intelligence, to its expression in self-directed anticipative learning in persons and in science.

Abstract

When psychotherapy is viewed as shared reconstruction, there are implications for both clients and therapists. My clients become sources of expectations, myths, thought, and feelings about themselves and their therapists. I, as therapist, become a source of intentions and reflections, with capacities for self-awareness and abilities to construe my clients and their constructs, languages, and metaphors. Both participants in psychotherapy can then be seen as involved in reconstruction through the sharing and rebuilding of narratives. It is the life stories of clients that are likely to be more changed in therapy, but my life stories and my stories about the therapeutic process are also open to change     

Employability capacities and organisational commitment foci of human resource professionals: An exploratory study

This study explored the relationship between employees’ employability capacities and their organisational commitment foci. A convenience sample of 196 South African human resource professionals participated in the study, consisting of 73% females and 88% black African people, predominantly within their early career stages (aged > 45 years). Data on individuals’ employability capacities and organisational commitment were collected via questionnaires. Canonical correlation analysis (CCA) was performed to assess the association between the variables of employability capacities and organisational commitment foci. Participants’ lifelong learning capacities (goal-directed behaviour and continuous learning orientation) were positively associated with their career commitment. This finding suggests that a strong lifelong orientation is likely to increase involvement in one’s occupation within the organisation, which contributes to organisational commitment. Lifelong learning capacities appear important to human resource professionals’ career development within their employer organisation.     

Contra Cartwright: Structural Realism, Ontological Pluralism and Fundamentalism About Laws

In this paper I argue against Nancy Cartwright’s claim that we ought to abandon what she calls “fundamentalism” about the laws of nature and adopt instead her “dappled world” hypothesis. According to Cartwright we ought to abandon the notion that fundamental laws (even potentially) apply universally, instead we should consider the law-like statements of science to apply in highly qualified ways within narrow, non-overlapping and ontologically diverse domains, including the laws of fundamental physics. For Cartwright, “laws” are just locally applicable refinements of a more open-ended concept of capacities. By providing a critique of the dappled world approach’s central notion of open ended capacities and substituting this concept with an account of properties drawn from recent writing on the subject of structural realism I show that a form of fundamentalism is viable. I proceed from this conclusion to show that this form of fundamentalism provides a superior reading of case studies, such as the effective field theory program (EFT) in quantum field theory, than the “dappled world” view. The case study of the EFT program demonstrates that ontological variability between theoretical domains can be accounted for without altogether abandoning fundamentalism or adopting Cartwright’s more implausible theses.     

Eyetracking for two-person tasks with manipulation of a virtual world

Eyetracking facilities are typically restricted to monitoring a single person viewing static images or prerecorded video. In the present article, we describe a system that makes it possible to study visual attention in coordination with other activity during joint action. The software links two eyetracking systems in parallel and provides an on-screen task. By locating eye movements against dynamic screen regions, it permits automatic tracking of moving on-screen objects. Using existing SR technology, the system can also cross-project each participant’s eyetrack and mouse location onto the other’s on-screen work space. Keeping a complete record of eyetrack and on-screen events in the same format as subsequent human coding, the system permits the analysis of multiple modalities. The software offers new approaches to spontaneous multimodal communication: joint action and joint attention. These capacities are demonstrated using an experimental paradigm for cooperative on-screen assembly of a two-dimensional model. The software is available under an open source license.     

The varieties of agential powers

The domain of agential powers is marked by a contrast that does not arise in the case of dispositions of inanimate objects: the contrast between propensities or tendencies on the one hand, and capacities or abilities on the other. According to Ryle, this contrast plays an important role in the “logical geography” of the dispositional concepts used in the explanation and assessment of action. However, most subsequent philosophers use the terms of art “power” or “disposition” indiscriminately in formulating central metaphysical claims about human agency, assuming that an adequate account of inanimate dispositions can safely be used for such purposes. As a result, the distinctive features of propensities and capacities drop out of view. This is bound to obscure distinctions of crucial importance to the understanding of human agency. In order to show this, I undertake to articulate some central differences between propensities and capacities. Propensities and capacities have a different relation to value, as well as a concomitant difference in their metaphysical structure. The argument points to an explanation of why the distinction between propensities and capacities does not arise in the case of non‐agential powers. This explanation takes us back to questions about the nature of human agency.     

Exploring the relationship between new word learning and short-term memory for serial order recall,item recall,and item recognition

We reexplored the relationship between new word learning and verbal short-term memory (STM) capacities, by distinguishing STM for serial order information, item recall, and item recognition. STM capacities for order information were estimated via a serial order reconstruction task. A rhyme probe recognition task assessed STM for item recognition. Item recall capacities were derived from the proportion of item errors in an immediate serial recall task. In Experiment 1, strong correlations were observed between item recall and item recognition, but not between the item STM tasks and the serial order task, supporting recent theoretical positions that consider that STM for item and serial order rely on distinct capacities. Experiment 2 showed that only the serial order reconstruction task predicted independent variance in a paired associate word–nonword learning task. Our results suggest that STM capacities for serial order play a specific and causal role in learning new phonological information.     

Components of Short-Term Memory and Their Relation to Language Processing

Abstract— Verbal working memory consists of separable capacities for the retention of phonological and semantic information. Within the phonological domain, there are independent capacities for retaining input-phonological codes and output-phonological codes. The input-phonological capacity does not appear to be critical for language comprehension but is involved in verbatim repetition and long-term learning of new words. The semantic capacity is critical for both comprehension and production and for the learning of new semantic information. Different neural structures appear to underlie these capacities, with a left-parietal region involved in input-phonological retention and a left-frontal region involved in semantic retention.     

Capacities, context and moral status of animals

According to a widely shared intuition, normal adult humans require greater moral concern than normal, adult animals in at least some circumstances. Even the most steadfast defenders of animals' moral status attempt to accommodate this intuition, often by holding that humans' higher-level capacities (intellect, linguistic ability, and so on) give rise to a greater number of interests, and thus the likelihood of greater satisfaction, thereby making their lives more valuable. However, the moves from capacities to interests, and from interests to the likelihood of satisfaction, have up to now gone unexamined and undefended. I argue that context plays a morally significant role both in the formation of an individual's capacities, and in the determination of the individual's interests and potential for satisfaction based on those capacities. Claims about an individual's capacities and interests are typically presented as unconditional; but on closer examination, they are revealed to be contingent on tacit assumptions about context. Until we develop an understanding of how to account for the role of context within our moral theories, attempts to defend special moral concern for human beings based on their superior capacities are less firmly grounded than is commonly thought.     

Anatomy of Regret: A Developmental View of the Depressive Position and a Critical Turn Toward Love and Creativity in the Transforming Schizoid Personality

This article deals with critical psychic transformation in a schizoid personality disorder that evolves in an object relations psychoanalysis in which "developmental mourning" plays a central role. Within a mourning process that allows for the grieving of loss related to arrested separation-individuation development, the analysand confronts the existential grief of regret that had always unconsciously haunted her. The unconscious guilt related to the existential grief of regret had caused much dissociation of self-experience and affect states. The analysand acknowledges her own part in the destruction of primal and current relationships after the traumatic impact of her early life is understood. This allows her to repair current relationships, both within her internal and external worlds so that she can open to capacities for love and creativity. The analysand's courage to consciously grapple with her regret (loss and guilt combined) allows her to relinquish self-sabotaging character defenses such as contempt and emotional withdrawl. Consequently, a second marriage is salvaged and enriched, and the analysand's relationship with her two children is dramatically improved.     

Mind perception of God in Japanese children

There is a theoretical debate regarding whether children represent God with reference to a human. Most previous studies have assessed this issue focusing on knowledge/omniscience in western children. This study used a theoretical framework characterising mental capacities in terms of motivational/emotional (experience) and cognitive (agency) mental capacities and tested whether Japanese children discriminated between God, a human, a baby and an invisible agent according to these capacities. Three‐ to 6‐year‐old children were asked about the experience and agency of the agents. The results revealed that children discriminated God from a human in terms of mental capacities including experience and agency in 3‐year‐old children. On the other hand, 4‐ to 6‐year‐old children, but not 3‐year‐old children, discriminated a human from a baby and an invisible person. The results suggest that the Japanese children's representations of God differed from their representation of a human during preschool years.     

But for the Grace of God: Abortion and Cognitive Disability,Luck and Moral Status

Many theories of moral status that are intended to ground pro-choice views on abortion tie full moral status to advanced cognitive capabilities. Extant accounts of this kind are inconsistent with the intuition that the profoundly cognitively disabled have full moral status. This paper improves upon these extant accounts by combining an anti-luck condition with Steinbock’s stratification of moral status into two levels. On the resulting view, a being has full moral status if and only if (1) she has moral status and (2) (a) has had advanced cognitive capacities, (b) has the potential to develop such capacities, or (c) would have had such capacities were it not for luck. I argue that modal accounts of luck provide a non-speciesist basis for attributing the lack of advanced cognitive capacities in humans to luck without doing the same for non-human animals.     

Ought we to require emotional capacity as part of decisional competence?

The preceding commentary by Louis Charland suggests that traditional cognitive views of decision-making competence err in not taking into account patients' emotional capacities. Examined closely, however, Charland's argument fails to escape the cognitive bias that he condemns. However, there may be stronger arguments for broadening the focus of competence assessment to include emotional capacities, centering on the ways in which emotions aid humans in processing information. Before emotional capacities are added to the list of functions essential for decisional competence, though, the feasibility and utility of such a reorientation must be demonstrated.     

Relating Coalition Capacity to the Adoption of Science-Based Prevention in Communities: Evidence from a Randomized Trial of Communities That Care

Coalition‐based efforts that use a science‐based approach to prevention can improve the wellbeing of community youth. This study measured several coalition capacities that are hypothesized to facilitate the adoption of a science‐based approach to prevention in communities. Using data from 12 coalitions participating in a community‐randomized trial of the prevention strategy Communities That Care (CTC), this paper describes select measurement properties of five salient coalition capacities (member substantive knowledge of prevention, member acquisition of new skills, member attitudes toward CTC, organizational linkages, and influence on organizations), as reported by coalition members, and examines the degree to which these capacities facilitated the community leader reports of the community‐wide adoption of a science‐based approach to prevention. Findings indicated that the five coalition capacities could be reliably measured using coalition member reports. Meta‐regression analyses found that CTC had a greater impact on the adoption of a science‐based prevention approach in 12 matched pairs of control and CTC communities where the CTC coalition had greater member (new skill acquisition) and organizational capacities (organizational linkages).     

Candidates' evaluation of psychoanalytic supervision

The origins, methods, results, and discussions of a project undertaken by the advanced candidates at the Denver Institute for Psychoanalysis have been described. This project was designed to examine the supervisory process and to compile a consensual critique of individual supervisors from the candidate's point of view. We have included vignettes of supervisory experiences. It became our purpose to: (1) Develop a set of criteria by which the strengths and weaknesses of supervisors can be evaluated, (2) Involve the candidate in assessing his own learning needs, (3) Promote the objective assignment of supervisors, an assignment determined by the patient's problems, the candidate's learning needs, and the supervisor's varying capacities and abilities to effectively understand these problems and deal with these needs, (4) Expand the supervisory process to include what we felt were often unconscious or hiterto unacceptable issues, such as the function and use of countertransference, and the detection and open discussion of transference dilemmas between analyst and both patient and supervisor, (5) Stimulate dialogue at all levels of psychoanalytic education on the patient-analyst-supervisor relational system.     

Biological preparedness and evolutionary explanation

It is commonly supposed that evolutionary explanations of cognitive phenomena involve the assumption that the capacities to be explained are both innate and modular. This is understandable: independent selection of a trait requires that it be both heritable and largely decoupled from other 'nearby' traits. Cognitive capacities realized as innate modules would certainly satisfy these contraints. A viable evolutionary cognitive psychology, however, requires neither extreme nativism nor modularity, though it is consistent with both. In this paper, we seek to show that rather weak assumptions about innateness and modularity are consistent with evolutionary explanations of cognitive capacities. Evolutionary pressures can affect the degree to which the development of a capacity is canalized by biasing acquisition/learning in ways that favor development of concepts and capacities that proved adaptive to an organism's ancestors.     

Human tool-making capacities reflect increased information-processing capacities: continuity resides in the eyes of the beholder

Chimpanzee/human technological differences are vast, reflect multiple interacting behavioral processes, and may result from the increased information-processing and hierarchical mental constructional capacities of the human brain. Therefore, advanced social, technical, and communicative capacities probably evolved together in concert with increasing brain size. Interpretations of these evolutionary and species differences as continuities or discontinuities reflect differing scientific perspectives.
