Positive conditioned suppression: an explanation in terms of multiple and concurrent schedules

Rats performed under a baseline variable-interval schedule of food presentation. A response-independent food schedule was then superimposed on the baseline schedule for different periods of time across different conditions. The response-independent schedule operated for the whole session in some conditions, intermittently for sixty second periods in some, and intermittently for ten-second periods in others. Under these latter two sets of conditions, the response-independent food schedule was stimulus correlated and alternated with the baseline schedule according to a multiple schedule. Response-independent food presentations always suppressed responding. The degree of suppression tended to increase the longer the period of response-independent food. Control conditions, in which the superimposed schedule was response-dependent, rather than response-independent, did not produce response suppression. The results fit an analysis of positive conditioned suppression phenomena in the context of multiple and concurrent schedule effects.     

An embodied model for sensorimotor grounding and grounding transfer: experiments with epigenetic robots

The grounding of symbols in computational models of linguistic abilities is one of the fundamental properties of psychologically plausible cognitive models. In this article, we present an embodied model for the grounding of language in action based on epigenetic robots. Epigenetic robotics is one of the new cognitive modeling approaches to modeling autonomous mental development. The robot model is based on an integrative vision of language in which linguistic abilities are strictly dependent on and grounded in other behaviors and skills. It uses simulated robots that learn through imitation the names of basic actions. Robots also learn higher order action concepts through the process of grounding transfer. The simulation demonstrates how new, higher order behavioral abilities can be autonomously built on previously grounded basic action categories following linguistic interaction with human users.     

Learning a new human-computer alphabet: the role of similarity and practice

Two purposes motivated this study: (a) to quantify the difficulty in learning various symbols of the alphabet used to enter data into a personal digital assistant (PDA), and (b) to investigate the interaction of item difficulty with practice conditions that promote varying levels of cognitive effort. Levels of compatibility between members of the PDA alphabet and English were quantified through introspective ratings in Experiment 1 and objective performance measures in Experiment 2. Three levels of item compatibility were learned under conditions of proactive or retroactive augmented information in Experiment 3. Contrary to expectations, the item similarity effect did not interact with practice schedules—a retroactive augmented information condition resulted in degraded levels of acquisition performance, but superior retention levels, compared to the proactive condition. These findings are discussed in terms of the relative merits of cognitive effort in skill acquisition.     

Infant Directed Speech in Natural Interaction—Norwegian Vowel Quantity and Quality

An interactive face-to-face setting is used to study natural infant directed speech (IDS) compared to adult directed speech (ADS). With distinctive vowel quantity and vowel quality, Norwegian IDS was used in a natural quasi-experimental design. Six Norwegian mothers were recorded over a period of 6 months alone with their infants and in an adult conversation. Vowel duration and spectral attributes of the vowels /a:/, /i:/ and /u:/, and their short counterparts /a/ /i/ and /u/ were analysed. Repeated measures analyses show that effects of vowel quantity did not differ between ADS and IDS, and for back vowel qualities, the vowel space was shifted upwards in IDS compared to ADS suggesting that fronted articulations in natural IDS may visually enhance speech to infants.     

Relationship of Attachment Style to Personality Factors and Family Interaction Patterns

This study investigated the relationships among attachment, personality style, and family interaction patterns. The results revealed that avoidant attachment style was associated with indirect affect expression as measured by somatic complaints, social isolation, family disengagement, and family conflict avoidance. Anxious/ambivalent style was associated with more overt expression of depression and anxiety. Family factors were not significantly related to either the anxious/ambivalent or secure styles. The implications and potential therapy benefits for use of attachment theory in family therapy and directions for future research are also addressed.

Gadamer and the Otherness of Nature: Elements for an Environmental Education

In this work I search for elements that contribute to the development of the ethical dimension of environmental education. I start with the existence of what C.A. Bowers calls “areas of silence” in the curriculum in both schools and universities. The reason for this silence, I argue, is to be found in the Cartesian conceptual structures of curricula. I suggest that the works of Bacon, Galileo and Descartes provoke a twofold process that I have termed the forgetting of tradition and objectification of nature. As a corrective to this process, I explore the possibilities that the philosophical hermeneutics of Hans-Georg Gadamer opens for rehabilitation of tradition and de-objectification of nature. I work with the concept of the “dignity of things” present in Greek dialectics: that nature is not simply a projection of mind (as the neo-Kantians claim), but something that thought suffers. In my conclusions I argue that for nature to be reinserted into almost all areas of knowledge it is necessary that we respect “the otherness of nature.”

Enlarging the model of the human at the heart of human-centered AI: A social self-determination model of AI system impact

Increasing awareness of the harms that artificial intelligence (AI) systems can cause has inspired a movement towards creating more human-centered AI (HCAI). One way in which AI systems can be made more human-centered is by focusing on the effects they have on people's needs. However, existing theories of technology impact in HCAI drawn from human-computer interaction (HCI) and related fields such as psychology are not able to account for the ways in which both needs and the impact of technology on these are dynamically shaped by the social context. To address this limitation, in this paper we outline a Social Self-Determination Model (SSDM) of AI system impact. SSDM proposes that people's needs for self-determination can be individual or collective in a particular context depending on features of the person and their environment. Accordingly, because AI systems treat people differently depending on the groups they belong to, they can make needs for individual or collective self-determination psychologically relevant and either fulfill or hamper these. SSDM can be used to help designers and developers create more human-centered AI systems by quantifying the effects of these systems and the social environment in which they are embedded on people's fundamental psychological needs and wellbeing.     

Dynamics of the dyad: How mothers and infants co-construct interaction spaces during object play

Studies of dyadic interaction often examine infants’ social exchanges with their caregivers in settings that constrain their physical properties (e.g., infant posture, fixed seating location for infants and adults). Methodological decisions about the physical arrangements of interaction, however, may limit our ability to understand how posture and position shape them. Here we focused on these embodied properties of dyadic interaction in the context of object play. We followed 30 mother–infant dyads across the first year of life (at 3, 6, 9, and 12 months) and observed them during 5 min of play with a standard set of toys. Using an interval-based coding system, we measured developmental change in infant posture, how mothers and infants positioned themselves relative to one another, and how they populated interaction spaces with objects. Results showed that mother–infant dyads co-constructed interaction spaces and that the contributions of each partner changed across development. Dyads progressively adopted a broader spatial co-orientation during play (e.g., positioned at right angles) across the first year. Moreover, advances in infants’ postural skills, particularly increases in the use of independent sitting in real time, uniquely predicted change in dyadic co-orientation and infants’ actions with objects, independent of age. Taken together, we show that the embodied properties of dyadic object play help determine how interactions are physically organized and unfold, both in real time and across the first year of life.     

Yoga-integrated psychotherapy for emotion dysregulation: A pilot study

Aims & Objectives

Yoga has been evidenced as beneficial for physical and mental health. This study sought to pilot the acceptability and feasibility of a yoga-integrated psychotherapy (YiP) intervention, aimed at alleviating difficulties in emotion regulation. A further aim was to explore the perceived effectiveness of YiP in alleviating depression, anxiety and improving well-being.

Methods

Seven participants who scored significantly on the Difficulties in Emotion Dysregulation Scale (DERS) took part in a psychological assessment session followed by six weekly one hr therapy sessions. Participants completed self-report measures in each session to quantify the effects of each YiP session on emotion regulation, well-being, depression and anxiety. Following seven sessions, five participants completed qualitative follow-up interviews to explore subjective experiences of YiP and any perceived impacts.

Findings

An ANOVA that contained data from seven participants who completed all six sessions revealed that DERS scores were significantly lower, and well-being scores were significantly higher, at both mid and end-points than at baseline. Thematic analysis of qualitative interviews identified five themes: “YiP assists the client's psychological and emotional processing,” “YiP improves insight and focus,” “YiP is culturally sensitive,” “the body facilitates regulation and resilience” and “YiP is acceptable & impactful.”

Conclusion

The study presents promising findings for the integration of yoga into psychotherapeutic practice and indicates that YiP may have beneficial effects on emotion regulation and psychological well-being. Future research should use randomised controlled methodologies to examine the ability of YiP to alleviate a wide range of affective symptoms using a larger sample of participants.
