A comparison of acceptance- and control-based strategies for coping with food cravings: an analog study

The present study utilized an analog paradigm to investigate the effectiveness of two strategies for coping with food cravings, which was theorized to be critical to the maintenance of weight loss. Ninety-eight undergraduate students were given transparent boxes of chocolate Hershey's Kisses and instructed to keep the chocolates with them, but not to eat them, for 48 h. Before receiving the Kisses, participants were randomized to receive either (a) no intervention, (b) instruction in control-based coping strategies such as distraction and cognitive restructuring, or (c) instruction in acceptance-based strategies such as experiential acceptance and defusion techniques. Measures included the Power of Food Scale (PFS; a measure of psychological sensitivity to the food environment), self-report ratings of chocolate cravings and surreptitiously recorded chocolate consumption. Results suggested that the effect of the intervention depended on baseline PFS levels, such that acceptance-based strategies were associated with better outcomes (cravings, consumption) among those reporting the highest susceptibility to the presence of food, but greater cravings among those who scored lowest on the PFS. It was observed that craving self-report measures predicted chocolate consumption, and baseline PFS levels predicted both cravings and consumption. Results are discussed in terms of the implications for weight loss maintenance strategies.     

Multilevel models for the experimental psychologist: Foundations and illustrative examples

Although common in the educational and developmental areas, multilevel models are not often utilized in the analysis of data from experimental designs. This article illustrates how multilevel models can be useful with two examples from experimental designs with repeated measurements not involving time. One example demonstrates how to properly examine independent variables for experimental stimuli or individuals that are categorical, continuous, or semicontinuous in the presence of missing data. The second example demonstrates how response times and error rates can be modeled simultaneously within a multivariate model in order to examine speed—accuracy trade-offs at the experimental-condition and individual levels, as well as to examine differences in the magnitude of effects across outcomes. SPSS and SAS syntax for the examples are available electronically.     

The impact of postpartum depressed mood on mother-infant interaction: Like mother like baby?

The purpose of this study was to test the hypothesis that mothers with depressed mood would exhibit less optimal interaction than their nondepressed counterparts and that their infants would show similar deficits in interactional behavior. Twenty-two mothers and their 2-month-old infants were videotaped in to-minute free-play segments in a laboratory playroom, and their interactions were coded using both time-sampling and global clinical ratings of behavior. Mothers with depressed mood were judged significantly lower on overall positive interaction, Expressivity/Affective Involvement, and Responsivity/ Sensitivity than were nondepressed mothers. Infants of mothers with depressed mood were rated significantly lower than infants of nondepressed mothers on corresponding interaction domains. Mothers with depressed mood were also rated as more variable than nondepressed mothers along a continuum of withdrawal to controlling/intrusive behavior. Contrary to prediction, level of maternal stimulation and infant activity did not differ as a function of depression in maternal mood. We conclude that mild to moderate symptoms of maternal depression may have salient but selective effects on mother-infant interaction.     

Amer-Ind versus ASL: recognition and imitation in aphasic subjects

The imitation and recognition ability of brain-damaged and normal subjects was tested for 30 pairs of semantically matched ASL signs and corresponding Amer-Ind gestures. Subjects were rated according to severity and site of lesion. They were 6 nonaphasic, right-hemisphere brain-damaged subjects, 12 aphasic subjects, and 12 non-brain-damaged geriatric subjects. Results indicated that the Amer-Ind gestures were significantly easier to imitate and to recognize than the matched ALS signs. The relationships between these gestural abilities and severity of aphasia, site of lesion, Amer-Ind transparency ratings, and subjects' performance on a standardized aphasia test are outlined. The theoretical implications that concern the neural systems which mediate spoken and limb gestures are discussed.     

Tree structures, the work of listening, and schizophrenic discourse: A reply to Beveridge and Brown

A. W. Beveridge and K. Brown (Brain and Language, 24, 174-181) have criticized a study reported by R. Hoffman, L. Kirstein, S. Stopek, and D. Cicchetti (Brain and Language, 15, 207-233), which examined processing tasks imposed upon listeners by schizophrenic speech. The authors argue that our discourse analysis was not sufficiently objective since different discourse structures can at times be generated on the basis of a particular deviant speech segment. However, the analysis which we described does not purport to yield an "objective" structure of schizophrenic texts but rather attempts to reflect representations that individual listeners generate in processing speech; our model only requires that different interpretations of a particular segment generate different discourse structures. Deficiencies in hierarchical structure associated with schizophrenic speech increase processing requirements for listeners and may cause interpretive variability. Incoherence scores generated on the basis of our analysis were used to estimate the amount of extra "work of listening" that particular speech segments require. Because these incoherence scores were blindly and reliably determined, they can be used to make statistical inferences about the prevalence of structural deficiencies of schizophrenic speech compared to the speech of controls.     

Higher Cost,Lower Validity and Higher Utility: Comparing the Utilities of Two Tests that Differ in Validity,Costs and Selectivity

Traditional approaches to comparing the utility of two tests have not systematically considered the effects of different levels of selectivity that are feasible and appropriate in various selection situations. For example, employers who hope to avoid adverse impact often find they can be more selective with some tests than with others. We conducted two studies to compare the utilities of two tests that differ in costs, validity, and feasible levels of selectivity which can be employed. First, an analytical solution was conducted starting with a standard formula for utility. This analysis showed that for both fixed and variable hiring costs, a higher-cost, lower-validity procedure can have higher utility than a lower-cost, higher-validity procedure when the selection ratios permissible using the two procedures are sufficiently (yet realistically) different. Second, using a computer simulation method, several combinations of the critical variables were varied systematically to detect the limits of this effect in a finite set of specific selection situations. The results showed that the existence of more severe levels of adverse impact greatly reduced the utility of a written test with relatively high validity and low cost in comparison with an assessment center with lower validity and higher cost. Both studies showed that the consideration of selectivity can yield surprising conclusions about the comparative utility of two tests. Even if one test has lower validity and higher cost than a second test, the first may yield higher utility if it allows the organization to exercise stricter levels of selectivity.     

Mothers' and Fathers' Gender-Role Characteristics: The Assignment of Postdivorce Child Care and Custody

Adults (151 female, 130 male; 17.4% African American/Black, 48% Caucasian, 22.8% Latino/Hispanic, 11.7% “other”) assigned postdivorce parental care and custody for four combinations of traditional/nontraditional mothers and fathers described in vignettes of divorcing parents. Parental gender characteristics influenced the assignment of parental care and child custody to divorcing mothers and fathers described in the scenarios and interacted with child gender. Across scenarios, female participants assigned more parental care and custody to mothers than did male participants. When feminine qualities were paired with masculine qualities, greater custody was assigned to the parent described with feminine characteristics (whether a father or mother) than when that parent was described with masculine characteristics. The role of feminine gender characteristics for child custody and care was discussed with regard to maternal primacy and possible changes for father involvement in the aftermath of divorce.
