The American Psychological Association's response to Brown v. Board of Education. The case of Kenneth B. Clark

In 1954, in Brown v. Board of Education, the Supreme Court struck down the "separate but equal" doctrine of the Plessy v. Ferguson decision (1896) that was the foundation of school segregation in 17 states and the District of Columbia. Brown is arguably the most important Supreme Court decision of the 20th century in terms of its influence on American history. Moreover, it has a special significance for psychology because it marked the first time that psychological research was cited in a Supreme Court decision and because social science data were seen as paramount in the Court's decision to end school segregation. This article describes psychologist Kenneth B. Clark's role in that case and the response of the American Psychological Association to scientific psychology's moment in a great spotlight.     

Use of the Beck Scale for suicide ideation with psychiatric inpatients diagnosed with schizophrenia,schizoaffective, or bipolar disorders

To ascertain how useful the Beck Scale for Suicide Ideation (BSI; Beck & Steer, Manual for Beck Scale for Suicide Ideation (1991)) would be for assessing the severity of suicidal ideation in patients who were diagnosed with schizophrenia, schizoaffective, or bipolar disorders, 142 inpatients were asked to complete the BSI. Eight (6%) patients refused, and four patients (3%) were unable to complete the BSI because they were unable to concentrate. Of the 130 patients who completed the BSI, 53 (41%) had schizoaffective, 37 (28%) had paranoid schizophrenia, 30 (23%) had manic bipolar, and 10 (8%) had depressed bipolar disorders. The coefficient alpha for the BSI was .96, and its one-week test-retest reliability for a subsample of 15 inpatients was 0.88, p < 0.001. The BSI total scores were positively correlated with having ever attempted suicide, r = 0.46, p < 0.001. According to the BSI, 36 (28%) patients were classified as current suicide ideators. The results were discussed as supporting the use of the BSI with inpatients who are diagnosed with schizophrenia, schizoaffective, or bipolar disorders.     

Learning and development in neural networks--the importance of prior experience

Infants can discriminate between familiar and unfamiliar grammatical patterns expressed in a vocabulary that is distinct from that used earlier during familiarization (Cognition 70(2) (1999) 109; Science 283 (1999) 77). Various models have captured the data, although each required that discrimination be distinct, in terms of the computational process, from familiarization. This article describes a simple recurrent network (SRN), equipped only with the assumption that it should predict what comes next, which models the data without distinguishing between familiarization and discrimination. To accomplish this, the SRN requires pre-training on a range of sequences instantiating different structures and different vocabulary items to those used subsequently during familiarization and test. Pre-training enables the network to avoid replacing structure acquired during familiarization with structure experienced at test. An equivalent enabling condition may underpin infants' resistance to catastrophic interference between the different structures and vocabulary items to which they are exposed.     

Can the Family Assessment Device (FAD) Be Used with School Aged Children?

This article examines the usefulness of the Family Assessment Device(FAD) in assessing family functioning with school-aged children (under 12 years of age) compared to children 12 and older and mothers. FAD reports from 194 children with asthma (132 under 12 years; 62 12 years and older) were evaluated in comparison to mothers' FAD reports as well as mothers' reports on two other family functioning measures: the Family Inventory of Life Events (FILE) and the Impact on Family (IOF) scale, both relevant to functioning in families with children with asthma. Although FAD scale reliabilities were lowest in younger children (alpha = 48-.79), good concurrent validity was found with mothers' reports on the three different measures of family functioning. Older childrens' FAD scales showed good reliability (> .70) but poorer agreement with the various maternal measures. With modifications to make items more structured and simplified, the FAD could be tried with younger children, although documentation of improved reliability is needed before more widespread use with school-aged children is advocated. The measure already shows good agreement with maternal report in this younger age group, which likely would be strengthened with improved reliability. FAD reports in older children correlated less well with maternal measures, but may represent nonredundant information on family health from an independent perspective and are worth considering in addition to mothers' perspectives.     

Dual-task attention deficits in dysphoric mood

The attentional functioning of nondysphoric, mildly dysphoric, and moderately to severely dysphoric college students was tested using the attentional blink (AB) paradigm. These groups performed equally well at reporting a single target appearing in a rapidly presented stream of stimuli. All groups showed an AB, with report sensitivity for a 2nd target being reduced when the 2 targets were presented less than 0.5 s apart. Nondysphoric and mildly dysphoric participants showed the same size ABs, but the ABs for moderately to severely dysphoric participants were larger and longer. As predicted, the results showed that moderately to severely dysphoric individuals have attentional impairments. These impairments, however, were evident only in the more demanding dual-task condition.     

Psychometric properties of the Chinese version of the Family Awareness Scale

The author examined the reliability and validity of the Chinese Family Awareness Scale (C-FAS) in 2 studies. In Study 1, data from 361 adolescents (a) showed that the C-FAS was temporally stable and internally consistent and (b) supported the concurrent and construct validities of the scale. In Study 2, data from clinical (N = 281) and nonclinical (N = 451) groups of adolescents showed that the C-FAS scores discriminated between the 2 groups. C-FAS scores were also correlated significantly with other measures of family functioning and psychological well-being. Results of the 2 studies suggest that the C-FAS displayed generally good psychometric properties in different samples of Chinese adolescents.     

Acceptability of personal hormone monitoring for contraception: longitudinal and contextual variables

A new contraceptive technology may advance the science of family planning but may do little to affect health if potential users do not deem it an acceptable method. The authors conducted an acceptability study of a newly developed contraceptive method--personal hormone monitoring. A sample of 480 English volunteers present at the 6th month of a 13-month longitudinal study completed surveys regarding their attitudes toward a personal hormone monitor for the purpose of contraception. The authors used the participants' responses to determine (a) the extent to which the participants accepted the monitor, (b) how their ratings of acceptability changed over time, (c) the extent to which contextual variables predicted changes in acceptability over time, and (d) whether those contextual variables predicted final acceptability of the monitor. Results suggested that no single method of family planning is best for everyone and specified the people for whom personal hormone monitoring may be most suitable.     

Effects of caffeine on performance of low intensity tasks

31 college age men and women who consume less than three caffeinated beverages per week agreed to participate as subjects in research on the effects of acute caffeine intake on low intensity task performance. All subjects performed two randomly administered test conditions: (1) caffeine (5 mg/kg) and (2) placebo on separate visits following an initial 1-hr. orientation visit. Subjects were administered the beverage 30 min. prior to performing 12 separate tests assessing basic mathematics, simple response, logical reasoning, hand-eye coordination, and spatial and assembly skills. The Spielberger State Anxiety test was administered immediately after consuming the test beverage and once again at posttest. Analysis showed that caffeine did not significantly affect performance on all tests with the exception of the peripheral awareness (hand-eye coordination) test on which performance was higher after ingesting caffeine. The placebo treatment produced no effect on state anxiety, which contrasted with a significant rise in anxiety after caffeine consumption. State anxiety values were significantly greater after caffeine treatment relative to the placebo at pretest, and this difference persisted at posttest. These results demonstrated that the dose of caffeine increased scores on state anxiety for individuals who consumed less than three caffeinated beverages weekly but had very little effect on performance of low intensity tasks, except for a hand-eye coordination test involving peripheral awareness. Perhaps longer continuous performance of more demanding tasks would be more sensitive.     

Relation of maximal ankle dorsiflexion angle and passive resistive torque to passive-elastic stiffness of ankle dorsiflexion stretch

The maximal passive ankle dorsiflexion angle and the maximal passive resistive torque at this angle were measured for 81 women 20 to 84 years of age and correlated with the passive-elastic stiffness (stiffness) of an ankle dorsiflexion stretch. Pearson correlation coefficients and multiple regression analyses were used to examine whether the two clinical measurements could predict ankle stiffness. The maximal passive resistive torque showed a moderate correlation with stiffness in the full stretch range (r = .69) and high correlation with stiffness in the last half of the full stretch range (r = .84). The maximal dorsiflexion angle showed a low correlation with stiffness in the full stretch range (r = .27) and in the last half of the full stretch range (r = .36). The maximal passive resistive torque and the dorsiflexion angle together accounted for 54% of the stiffness variance in the full stretch range and 76% of the stiffness variance in the last half of the full stretch range. Thus, the clinical measurements of the maximal passive dorsiflexion angle and the maximal passive resistive torque were directly and significantly related to the ankle dorsiflexion passive-elastic stiffness and good predictors of stiffness in the last half of the passive ankle dorsiflexion stretch.
