Discrimination of individual vocalizations by black-capped chickadees (Poecile atricapilla)

The auditory perceptual abilities of male black-capped chickadees (Poecile atricapilla) were examined using an operant go/no-go discrimination among 16 individual vocalizations recorded at 5 m. The birds learned to discriminate about equally well among eight male chickadee fee-bee songs and eight female zebra finch (Taeniopygia guttata) distance calls. These results do not indicate that chickadees have a species-specific advantage in individual recognition for conspecific over heterospecific vocalizations. We then transferred the chickadees to a discrimination of the same songs and calls rerecorded at a moderate distance. These results showed accurate transfer of discrimination from 16 vocalizations recorded at 5 m to novel versions of the same 16 songs and calls rerecorded at 25 m. That is, chickadees recognized individual songs and calls despite degradation produced by rerecording at 25 m. Identifying individual vocalizations despite their transformation by distance cues is here described as a biologically important example of perceptual constancy.     

PSYCHOANALYSIS AND INFERTILITY MYTHS AND REALITIES

Psychoanalysis, long interested in infertility, and a valuable treatment for men and women suffering with this affliction, has also helped to create and support a myth of psychogenic infertility. Multiple causes of infertility exist across the physiological - psychological spectrum. There is no simple psychodynamic causality. Advances in assisted reproductive technologies provide treatments that create emotional stress and outpace psychological preparedness of patients and analysts. This paper is based on the experience of a unique study group in Boston. An analytic case illustrates some of the ways analysis can be a treatment of choice for people using assisted reproduction. In fact, analysis offers a unique opportunity to elaborate fully the complex realities and dilemmas faced by people and their therapists throughout the infertility experience. More generally, this study of the concept of psychogenic infertility explores a valuable role for psychoanalysis in the treatment of medical conditions.     

Learning directions of objects specified by vision,spatial audition,or auditory spatial language

The modality by which object azimuths (directions) are presented affects learning of multiple locations. In Experiment 1, participants learned sets of three and five object azimuths specified by a visual virtual environment, spatial audition (3D sound), or auditory spatial language. Five azimuths were learned faster when specified by spatial modalities (vision, audition) than by language. Experiment 2 equated the modalities for proprioceptive cues and eliminated spatial cues unique to vision (optic flow) and audition (differential binaural signals). There remained a learning disadvantage for spatial language. We attribute this result to the cost of indirect processing from words to spatial representations.     

Self-recognition: body and action

How do I know it was me who moved? A recent experimental study illustrates the contribution of one's body schema and awareness of one's own actions to self-recognition. The results provide evidence that bodily cues and action cues are important in self-recognition, and they demonstrate that action cues overrule bodily cues.     

On the complexity of classical guitar playing: functional adaptations to task constraints

The authors performed a behavioral study of the complexity of left-hand finger movements in classical guitar playing. Six professional guitarists played movement sequences in a fixed tempo. Left-hand finger movements were recorded in 3 dimensions, and the guitar sound was recorded synchronously. Assuming that performers prefer to avoid extreme joint angles when moving, the authors hypothesized 3 complexity factors. The results showed differential effects of the complexity factors on the performance measures and on participants' judgments of complexity. The results demonstrated that keeping the joints in the middle of their range is an important principle in guitar playing, and players exploit the available tolerance in timing and placement of the left-hand fingers to control the acoustic output variability.     

Psychosocial predictors of anxiety among immigrant Mexican migrant farmworkers: implications for prevention and treatment

This study examined predictors of anxiety symptomatology among immigrant Mexican migrant farmworkers in the Midwest. Its purposes were to assess the prevalence of anxiety symptoms, to examine the relationship between acculturative stress and anxiety, and to determine the variables that best predict anxiety. Heightened levels were found for overall anxiety and in the cognitive, affective, and physiological expressions of anxiety. Elevated acculturative stress, low self-esteem, ineffective social support, lack of control and choice in living a migrant farmworker lifestyle, low religiosity, and high education were significantly related to high anxiety. Findings suggest that migrant farmworkers who experience elevated acculturative stress are susceptible to the development of anxiety-related disorders and highlight the importance of establishing prevention and treatment services for migrant farmworkers.     

Personality Dysfunction and the Management of Chronic Medical Illness: A Community Health Sample

The purpose of this study was to determine the influence of personality disorders on perceived health status, self-efficacy for management of the chronic illness, and physician perception of patient health. A total of 607 patients with self-identified chronicillness(es) volunteered to participate in the study. Out of this sample, 147 had collaborative physician data indicating a chronic illness. The final sample was 143 due to incomplete data. Results suggested that maladaptive personality characteristics, as measured by the Short-Form of the Coolidge Axis II Inventory (SCATI), were related to a number of important factors that influence self-management of chronic illnesses. When the personality constellations were broken into 3 groups (normal, subclinical, and clinical) significant differences were found on the 3 groups of dependent variables (Subjective Health, Self-Efficacy, Physician Appraisal) for the different personality disorders. These data provide useful information on several factors that influence effective disease management. Clinical implications and directions for future research are provided.     

The Transracial Adoption Debate: Counseling and Legal Implications

Over the last 30 years, the practice of White American parents adopting African American children has been the focus of much deliberation and commentary. In this article, the authors illuminate relevant literature and research regarding transracial adoption. Counseling and legal implications are also discussed.     

Is how it is said important? The association between quality of therapist interventions and client processing

This study examined the association between the quality of therapist interventions and client in‐session processing using the York Therapist Process Measure (YTPM; Toukmanian and Armstrong, 1998). The instrument's three dimensions — attunement, tentativeness and meaning exploration — were tested separately for their impact on clients' manner of processing and depth of experiencing. For each of the 20 mild‐moderately depressed clients, treated in short‐term experiential therapy, a high and a low client‐process segment was isolated from a session that was judged by an experienced therapist to manifest the greatest amount of “good therapy moments”. Therapist interventions within these segments were then rated on the YTPM. Results revealed significant differences in the quality of therapist interventions between high and low segments. Attunement and tentativeness were associated significantly with greater complexity in manner of processing, and meaning exploration with greater depth in experiencing. The implications of these findings for psychotherapy research and practice are discussed.     

A cognitive model of insomnia

Insomnia is one of the most prevalent psychological disorders, causing sufferers severe distress as well as social, interpersonal, and occupational impairment. Drawing on well-validated cognitive models of the anxiety disorders as well as on theoretical and empirical work highlighting the contribution of cognitive processes to insomnia, this paper presents a new cognitive model of the maintenance of insomnia. It is suggested that individuals who suffer from insomnia tend to be overly worried about their sleep and about the daytime consequences of not getting enough sleep. This excessive negatively toned cognitive activity triggers both autonomic arousal and emotional distress. It is proposed that this anxious state triggers selective attention towards and monitoring of internal and external sleep-related threat cues. Together, the anxious state and the attentional processes triggered by it tricks the individual into overestimating the extent of the perceived deficit in sleep and daytime performance. It is suggested that the excessive negatively toned cognitive activity will be fuelled if a sleep-related threat is detected or a deficit perceived. Counterproductive safety behaviours (including thought control, imagery control, emotional inhibition, and difficulty problem solving) and erroneous beliefs about sleep and the benefits of worry are highlighted as exacerbating factors. The unfortunate consequence of this sequence of events is that the excessive and escalating anxiety may culminate in a real deficit in sleep and daytime functioning. The literature providing preliminary support for the model is reviewed and the clinical implications and limitations discussed.
