Response latency as a function of reinforcement schedule

Four Ss were trained to press and hold down a telegraph key in the presence of a light. Subsequent release of the key during a tone was followed by water reinforcement. The schedule of reinforcement for key release was varied, and its effects on the latency (RT) of key release to the tone were studied. Both median RT and variability of RT were found to be inversely related to frequency of reinforcement as determined by the schedule.     

A Psychometric Investigation of the Suicide Status Form II with a Psychiatric Inpatient Sample

We investigated the psychometric validity and reliability of the Suicide Status Form‐II (SSF‐II) developed by Jobes, Jacoby, Cimbolic, and Hustead (1997) . Participants were 149 psychiatric inpatients (108 suicidal; 41 nonsuicidal) at the Mayo Clinic. Each participant completed assessment measures within 24 hours of admission and 48–72 hours later. Factor analyses of the SSF core assessment produced a robust two‐factor solution reflecting chronic and acute response styles. The SSF core assessment had good to excellent convergent and criterion validity; pre‐post SSF ratings also demonstrated moderate test‐retest reliability. The results replicated previous research and show that the SSF‐II is psychometrically sound with a high‐risk suicidal inpatient sample.     

SOME VIEWPOINTS ON WOMAN'S INNER SPACE

In this paper, illusion is examined as a prerequisite and necessary medium for the analysand's finding the genuine subjective reality of his own in the psycho-analytic interaction. Two kinds of illusion are discussed The first of them, transference illusion, is well-known, as is its understanding as a simultaneous existence of experiences stemming from different levels of reality. At its side, the author introduces the concept of developmental illusion, as an essential constituent of the analytic process. As contrasted to transference illusion, the wishes inherent in a developmental illusion have never become meaningfully represented in the analysand's mind. These interrupted developmental needs attaining shape and meaning, and thus the possibility to develop further in the analytic relationship, is dependent on the analyst's ability and ways to receive and meet the analysand's activated developmental illusion. The rôle of the analyst's ways to reach and convey his understanding is considered decisive in this process.     

The impact of words on children with ADHD and DAMP Consequences for psychoanalytic technique

Children with attention-defi cit/hyperactivity disorder (ADHD) and disorder of attention, motility control, and perception (DAMP) are often sensitive to the analyst's interventions. This is not always due to the literal import of the intervention. The children sometimes react as if the words were dangerous concrete objects, which they must physically fend off. The author traces this phenomenon to the child's unstable internal situation. A bad, un-containing internal object is easily awakened and threatens to expel the analyst's words independently of their content. This results in violent clinical situations. Infant research and psychoanalytic work with infants and mothers evince how a complex semiotic process develops between mother and baby. The prerequisite for this process to get started and maintained is a secure external object, which gradually is internalized. Findings from developmental research and clinical infant work are used to illuminate analytic work with children with ADHD and DAMP. Vignettes demonstrate how important it is for the analyst to phrase interpretations after having gauged the state of the analysand's internal object as well as his/her own countertransference. If this is overlooked, the psychoanalytic dialogue easily capsizes. The author provides some technical recommendations on the psychoanalysis of these children. As part of the theoretical discussion he raises the general question of how the representations, which the baby forms in interaction with the mother, and the analysand forms in interaction with the analyst, should be classifi ed. Rather than dividing them into bipartite thing- or word-presentations (Freud), the author suggests C. S. Peirce's tripartite semiotic classifi cation in that the baby forms representations of icons, indices, and symbols.     

Problems in contemporary psychoanalytic theory: II. Lines of advance

In the theoretical development to come in psychoanalysis, an "inclusive" strategy is recommended, allowing for conflicting points of view to exist side by side waiting for a new integrating theory to emerge. Until such a theory is at hand, the term "psychoanalysis" will remain a rather loose heading for several psychoanalytic subcultures. It is argued, both clinically and theoretically, in favour of giving the organizing function of the ego a central position in the forthcoming theory. Some consequences of this "organizational" point of view are discussed in relation to: ( a ) diagnostic classification, ( b ) the distinction between psychoanalysis and psychoanalytically oriented psychotherapy, and (c) the theoretical language of psychoanalysis. In conclusion som requirements for a future theory of psychoanalysis are proposed.     

Taste/tactile cue discriminations in taste-aversion learning foIIowing depletion of noradrenaIine

Four experiments were performed to investigate the effect of noradrenaline (NA) depletion, following systemic DSP4 treatment, upon a tastehactile discrimination in taste-aversion learning. In Experiments 1 and 2 , noisy bottle (A) + lithium chloride pairings were alternated with saccharin (B) + saline pairings, and vice versa, during Phase I conditioning. The particular order of reinforcement presentation in each case was then reversed, so that a noisy bottle (A) + saline pairing was now altered with a saccharin (B) + lithium chloride pairing, etc., during Phase II (reversal) conditioning. In Experiments 3 and 4 , saccharin in noisy bottle (AB) + lithium chloride pairings alternated with either noisy bottle (A) + saline or saccharin (B) + saline pairings, and vice versa, during Phase I conditioning; the order of reinforcement presentation was then reversed, as above. None of the four experiments performed offered any evidence of impairments of the discrimination task as a result of NA depletion. These results are discussed in the context of associative preparedness and of discrimination learning in operant tasks and recent findings on compound conditioning, following the loss of NA.     

Fear questionnaires for simple phobias: Psychometric evaluations for a Norwegian sample

The present study presents psychometric data for four different phobic fear questionnaires in a Norwegian sample of 284 subjects. The questionnaires concerned fear of flying, snakes, spiders and a questionnaire of general phobic complaints. The results showed a high estimate of internal consistency, and a very high test-retest reliability for all questionnaires. A low to moderate degree of intercorrelation between the questionnaires appeared. A clear sex difference emerged in responding to all four questionnaires. In addition, a clinical sample of phobics with fear of flying as the main symptom was compared to the larger sample on a fear of flying scale. The results showed a clear difference in responding between the samples. The present study concludes that the four different fear questionnaires yielded a high degree of reliability, and their use in clinical practice is encouraged.     

Scotopic contrast hues displaced toward red

Stabell, B. & Stabell, U. Scotopic contrast hues displaced toward red. Scand. J. Psychol., 1973, 14, 316–319.-The displacement of scotopic contrast hues toward red, contrary to predictions based on the opponent color theory of Hering, is explained on the assumption that the violet receptor system has a negligible sensitivity at the yellow cardinal point, while all the receptor systems are activated at the blue cardinal point.     

Scotopic and photopic afterimages

Stabell, U. & Stabell, B. Scotopic and photopic afterimages. Scand. J. Psychol., 1973, 14, 210–212.MdashThe curves of photopic and scotopic afterimages were found to coincide, confirming the suggestion that disposition for scotopic contrast hue is controlled basically by the ratio of hue-related processes initiated upon chromatic prestimulation of cones, while the achromatic test-stimulation is a constant stimulus, regardless of test variables.     

Attitudes towards the old and death,and spiritual well-being

The purpose of this research was to determine the interrelationship of attitudes towards older people, death attitudes, and the spiritual well-being of 300 nursing students. Instruments employed were Kogan's Old People Scale, the Death Anxiety Scale, the Death Depression Scale, and the Spiritual Well-being Scale. Pearson product-moment correlation coefficients and multiple-regression analysis were used to test the hypotheses. Hypotheses were supported predicting an inverse relationship between attitudes towards older people and death anxiety and death depression (p<.01), and a positive relationship between spiritual well-being and negative attitude towards older people (p<.01). Data did not support the hypothesis that death attitudes and spiritual well-being would account for greater variance in attitudes towards older people than either single variable alone. From a step-wise multiple-regression analysis, race/ethnicity and death attitudes together accounted for 21% of the variance in attitudes towards older people. Study results demonstrated that Caucasian nursing students hold positive attitudes toward older people. Implications for health care are discussed with particular emphasis on potential strategies for education.
