A feeding scale for research and clinical practice to assess mother—infant interactions in the first three years of life

The Feeding Scale provides a reliable rating of mother-infant/toddler interactions during a 20-minute feeding in a laboratory setting. The scale consists of 46 mother and infant behaviors, which are rated at the end of the feeding session. Observations of mother—infant interactions during two feedings separated by 2 weeks showed considerable stability. Five subscale scores are derived (1) Dyadic Reciprocity, (2) Dyadic Conflict, (3) Talk and Distraction, (4) Struggle for Control, and (5) Maternal Non-Contingency, Predictive validity of the Feeding Scale has been demonstrated and it discriminates between infants with and without feeding disorders as well as three diagnostic categories of feeding-disordered infants. The Feeding Scale can be used with infants and toddlers ranging in age from 1 month to 3 years. © 1997 Michigan Association for Infant Mental Health     

Sleep Loss and Temporal Memory

Historical evidence suggests that sleep deprivation affects temporal memory, but this has not been studied systematically. We explored the effects of 36 hr of sleep deprivation on a neuropsychological test of temporal memory. To promote optimal performance, the test was short, novel, and interesting, and caffeine was used to reduce 'sleepiness'. A total of 40 young adults were randomized into four groups: control + caffeine (Cc), control + placebo (Cp), sleep deprived + caffeine (SDc), and sleep deprived + placebo (SDp). Controls slept normally. Caffeine (350 mg) or placebo were given just prior to testing. The task comprised colour photographs of unknown faces and had two components: recognition memory (distinction between previously presented and novel faces), and recency discrimination (temporal memory), when a previously shown face was presented. An interpolated task, self-ordered pointing, acted as a distraction. Caffeine had no effects within control conditions, but significantly reduced subjective sleepiness in SDc. Recognition was unaffected by sleep deprivation, whereas for recency, sleep deprivation groups scored significantly lower than controls. There was no significant improvement of recency with caffeine in the SDc group. Both sleep deprivation groups had poorer insight into their performance with recency. Self-ordered pointing remained unchanged. In conclusion, sleep deprivation impairs temporal memory (i.e. recency) despite other conditions promoting optimal performance.     

A biochemical analysis of people with chronic fatigue who have Irlen Syndrome: speculation concerning immune system dysfunction.

This study investigated the biological basis of visual processing disabilities in adults with Chronic Fatigue Syndrome. The study involved 61 adults with symptoms of Chronic Fatigue Syndrome who were screened for visual processing problems (Irlen Syndrome) and divided into two groups according to the severity of symptoms of Irlen Syndrome. Significant variations were identified in blood lipids and urine amino and organic acids of the two groups, which may be indicative of activation of the immune system due to some infective agent. It was suggested that metabolic profiling may help the development of more valid diagnostic categories and allow more investigation of immune system dysfunction as a possible causal factor in a range of learning and behaviour disorders.     

Relationships Between Attitudes Toward Organizations and Performance Appraisal Systems and Rating Behavior

Data collected in seven separate samples in three countries (the USA, Canada and Israel) were used to examine the relationships between perceptions of one’s organization (climate, commitment), beliefs about appraisal systems (self‐efficacy, uses of appraisal) and raters’ orientations to appraisal systems (confidence and comfort) and specific rating behaviors. We obtained good fits for structural models suggesting that attitudes and beliefs accounted for substantial variance in raters’ likelihood of giving high or low ratings, willingness to discriminate good from poor performers, and willingness to discriminate among various aspects of job performance when completing actual performance ratings. Proximal attitudes and beliefs (i.e., those directly related to the performance appraisal system) appear to have stronger links to rating behavior than do more distal attitudes (i.e., attitudes toward the organization in general).     

Mental Illness, Motivation and Moral Commitment

I present a dilemma which depressive behavioural pathology poses for both Humean and non-Humean theories of motivation and value. Although the dilemma shows that neither theory can be considered adequate in its standard form, I argue that if the Humean theory is modified so as to embrace a richer notion of satisfaction than it currently does, it can solve the problem which depression poses for it, and thus the dilemma can be avoided. Embracing a richer notion of satisfaction not only solves this problem, it also extends the scope of the Humean theory in a potentially dramatic way, by extending the explanatory reach of moral psychology to issues often thought to fall outside its scope, namely, issues in moral psychopathology.     

Analysis and treatment of finger sucking

We analyzed and treated the finger sucking of 2 developmentally typical children aged 7 and 10 years. The functional analysis revealed that the finger sucking of both children was exhibited primarily during alone conditions, suggesting that the behavior was maintained by automatic reinforcement. An extended analysis provided support for this hypothesis and demonstrated that attenuation of stimulation produced by the finger sucking resulted in behavior reductions for both children. Treatment consisted of having each child wear a glove on the relevant hand during periods when he or she was alone. Use of the glove produced zero levels of finger sucking for 1 participant, whereas only moderate reductions were obtained for the other. Subsequently, an awareness enhancement device was used that produced an immediate reduction in finger sucking.
