A THERAPEUTIC PLAYGROUP FOR DEPRESSED MOTHERS AND THEIR INFANTS: FEASIBILITY STUDY AND PILOT RANDOMIZED TRIAL OF COMMUNITY HUGS

Symptoms of depression negatively impact on mother?infant relationships and child outcomes. We evaluated a novel, 10‐session mother?infant therapeutic playgroup—Community HUGS (CHUGS)—which combines cognitive and experiential components through psychoeducation, play, music, and movement. Participants were mothers experiencing a range of postnatal mental health difficulties, including depression, with infants ≤12 months of age. However, the aim was not to treat maternal depression but to ameliorate associated problems in the mother?infant interaction. In the feasibility study, all participants received CHUGS. In the pilot randomized controlled trial (RCT), participants were randomized between intervention and a wait‐list. Outcomes were the Parenting Stress Index (PSI; R.R. Abidin, 1995), Parenting Sense of Competency Scale (Self‐Efficacy subscale; J. Gibaud‐Wallston & L.P. Wandersman, 1978), and the Depression, Anxiety, Stress Scales (P.F. Lovibond & S.H. Lovibond, 1995). In the feasibility study (n = 74), PSI scores dropped on all subscales, all ps < .01. Depression, p < .001, anxiety, p = .01, stress, p = .01, and self‐efficacy, p < .001, all showed improvements, as did observer‐rated mother?infant interactions, p < .001. In the RCT, depression, p < .001, anxiety, p = .005, and stress, p < .001, symptoms were significantly reduced for intervention participants (n = 16), as compared to wait‐list participants (n = 15). The CHUGS program had high participant satisfaction and produced improvements in self‐efficacy, depression, anxiety, stress, and mother?infant interactions that supported the program's acceptability and the utility of further rollout.     

Postmodernism: Its Origins and its Threat to Psychoanalysis

Postmodernism originated in an overreaction to "modernist" sociocultural trends of the past few centuries. Flaws of postmodern writers include: ignorance and distortion of the history of science and philosophy; the erroneous assumption that such faults of some natural scientists as reductionism and narrowness are intrinsic to the entire enterprise, even to rationality; overgeneralizing such valid criticisms to the level of metaphysical relativism; and deliberately obscure and pretentious writing. Its vogue is a threat to science in general and to psychoanalysis in particular. Psychoanalysis was vulnerable to a postmodernist attack because of Freud's rejection of scientific standards for his creation, his na¨ L ve realism, and his authoritarian heritage plus certain weaknesses of theory, technique, and organization resulting from it. Analysts are urged to stay close to clinical observation and abstain from generalizing outside their realm of expertise.     

Digital Drift and the “Sense of Injustice”: Counter-Productive Policing of Youth Cybercrime

ABSTRACT

Over the past several decades, criminological scholarship has increasingly focused on the problem of cybercrime including technology-enabled offending. Theoretical developments that account for these offences have not grown in tandem, leading to questions as to the nature of cybercriminality relative to traditional forms of offending. Recently, Goldsmith and Brewer proposed the conceptual framework of digital drift, extending elements of Matza’s original theories to the virtual environment. While making a useful contribution to the theorization of cybercrime, we argue that further elements of Matza’s original work also warrant consideration. In particular, we acknowledge the role of policing and the criminal justice system in affecting offender perceptions and decision-making. As such, this article extends the theorizing around digital drift to incorporate the ways that offender views are shaped in reaction to the law enforcement and industry responses to cybercrime. The implications of this extension are discussed in depth.     

A lifelong attempt to understand and assess personality

The author recounts the story of his life and career in clinical psychology from 1917 to 2003. He offers hypotheses about parts of his personal life that may have predisposed him to develop a special interest in assessing personality, discusses formative influences on his particular approach to the topic, and describes the settings in which and some of the colleagues with whom he participated in some principal pieces of research on this aspect of psychology.     

Developmental trajectory of dynamic resource utilization during walking: toddlers with and without Down syndrome

After years of walking practice 8-10-year-old children with typical development (TD) and those with Down syndrome (DS) show uniquely different but efficient use of dynamic resources to walk overground and on a treadmill [Ulrich, B.D., Haehl, V., Buzzi, U., Kubo, M., & Holt, K.G. (2004). Modeling dynamic resource utilization in populations with unique constraints: Preadolescents with and without Down syndrome. Human Movement Science, 23, 133-156]. Here we examined the use of global stiffness and angular impulse when walking emerged and across the ensuing months of practice in eight toddlers with TD and eight with DS. Participants visited our lab when first able to walk four to six steps, and at one, three, four, and six months of walking experience. For all visits, toddlers walked overground at their preferred speeds and for the last two visits on a treadmill. Toddlers with TD and DS demonstrated clear and similar developmental trajectories over this period with more similarities than differences between groups. At six months stiffness and impulse values were higher than previously observed for 8-10-year-old children. Stiffness values increased significantly throughout this period, though rate of change slowed for the TD group by three months of experience. Impulse values rose sharply initially and slowed to plateau during the latter months. Treadmill data illustrated toddlers' capacity to adapt dynamic resource use to imposed changes in speed, particularly well after six months of practice. Consistent with our studies of preadolescents and older adults, toddlers with DS produced significantly wider normalized step width than their TD peers. We propose that the challenge of upright bipedal locomotion constrains toddlers with TD and DS to generate similar, necessary and sufficient stiffness and impulse values to walk as they gain control and adapt to playful and self-imposed perturbations of gait over the first six months. The plateau in impulse and slow-down of stiffness increases over the latter months may be the first signs of a downward trend to the lower values produced by older children with several years of walking experience.     

Hemispheric asymmetries in children's perception of nonlinguistic human affective sounds

In the present work, we developed a database of nonlinguistic sounds that mirror prosodic characteristics typical of language and thus carry affective information, but do not convey linguistic information. In a dichotic-listening task, we used these novel stimuli as a means of disambiguating the relative contributions of linguistic and affective processing across the hemispheres. This method was applied to both children and adults with the goal of investigating the role of developing cognitive resource capacity on affective processing. Results suggest that children's limited computational resources influence how they process affective information and rule out attentional biases as a factor in children's perceptual asymmetries for nonlinguistic affective sounds. These data further suggest that investigation of perception of nonlinguistic affective sounds is a valuable tool in assessing interhemispheric asymmetries in affective processing, especially in parceling out linguistic contributions to hemispheric differences.     

Expertise and its embodiment: Examining the impact of sensorimotor skill expertise on the representation of action-related text

In two experiments, we explored how novice and expert athletes represent the everyday and sportspecific objects and actions that they read about. Novice and expert ice hockey players (Experiment 1) and football players (Experiment 2) read sentences describing everyday or sport-specific situations and then judged whether a pictured item (either matching the action implied in the previous sentence or not) was mentioned in the preceding sentence. The sentences in Experiment 1 consisted of everyday and hockey-specific scenarios. The sentences in Experiment 2 depicted football scenarios implying football-specific or non—football-specific actions anyone might perform. Everyone responded most quickly to items that matched the sentence-implied actions for everyday and non—sport-specific actions. Only athletes showed this effect for their respective sport-specific scenarios. Differentiating between the same item in different action orientations is thought to be driven by embodied knowledge containing the sensorimotor characteristics of what one is reading about. We show that possessing this type of representation depends on experience interacting with objects and performing the actions in question.     

An interactive Hebbian account of lexically guided tuning of speech perception

We describe an account of lexically guided tuning of speech perception based on interactive processing and Hebbian learning. Interactive feedback provides lexical information to prelexical levels, and Hebbian learning uses that information to retune the mapping from auditory input to prelexical representations of speech. Simulations of an extension of the TRACE model of speech perception are presented that demonstrate the efficacy of this mechanism. Further simulations show that acoustic similarity can account for the patterns of speaker generalization. This account addresses the role of lexical information in guiding both perception and learning with a single set of principles of information propagation.

Economic and biological influences on key pecking and treadle pressing in pigeons

Pigeons were studied on a two-component multiple schedule in which the required operant was, in different conditions, biologically relevant (i.e., key pecking) or nonbiologically relevant (i.e., treadle pressing). Responding was reinforced on a variable-interval (VI) 2-min schedule in both components. In separate phases, additional food was delivered on a variable-time (VT) 15-s schedule (response independent) or a VI 15-s schedule (response dependent) in one of the components. The addition of response-independent food had different effects on responding depending on the operant response and on the frequency with which the components alternated. When components alternated frequently (every 10 s), all pigeons keypecked at a much higher rate during the component with the additional food deliveries, whether response dependent or independent. In comparison, treadle pressing was elevated only when the additional food was response dependent; rate of treadling was lower when the additional food was response independent. When components alternated infrequently (every 20 min), pigeons key pecked at high rates at points of transition into the component with the additional food deliveries. Rate of key pecking decreased with time spent in the 20-min component when the additional food was response independent, whereas rate of pecking remained elevated in that component when the additional food was response dependent. Under otherwise identical test conditions, rate of treadle pressing varied only as a function of its relative rate of response-dependent reinforcement. Delivery of response-independent food thus had different, but predictable, effects on responding depending on which operant was being studied, suggesting that animal-learning procedures can be integrated with biological considerations without the need to propose constraints that limit general laws of learning.
