ABSTRACT
The difference in attention and cognitive performance between 26 hypotensive (systolic blood pressure < 100 mmHg and diastolic blood pressure < 60 mmHg) and 22 normotensive female university students was assessed. Attention was examined with contingent negative variation (CNV) recorded using light and tone as S1 and S2. Cognitive performance was assessed by free recall of a list of words and two German tests of cognitive speed performance and sustained attention: Zahlen-Verbindungs-Test and d2. The hypotensive participants demonstrated a lower increase in negativity on the CNV. Moreover, in the free recall test, hypotensive individuals remembered fewer words, in comparison with normotensive subjects. Scores for hypotensive individuals on the Zahlen-Verbindungs-Test and d2 were also lower. No difference was found in reaction times to imperative stimuli (S2).

The ability of congenitally blind persons to produce voluntarily facial expressions of a number of emotions was compared with that of normally sighted individuals using both objective facial measurement and observer recognition. Results revealed that there were almost no significant differences between blind and sighted participants with respect to the number and type of facial action units produced. The portrayals of the blind participants were significantly more poorly recognized by observers than were those of the sighted participants (except for happiness). Correspondence analyses of the data showed differences between sighted and blind participants in the dimensional structure of the expressions (as based on the similarity among emotions with respect to both objective measurement and judgments). Overall, the data relavitize earlier conclusions on the facial expression of blind as compared with sighted persons and suggest specific hypotheses and procedures for further work in this area.

Anger and hostility have long been considered important factors in the etiology of essential hypertension (EH) and coronary heart disease (CHD). This case-control study investigates the association of hostility, as measured by the Cook and Medley Hostility Scale (HO), and anger, as measured by the Multidimensional Anger Inventory (MAI), with CHD and EH in 80 CHD patients, 80 EH patients, and a control group of 80 healthy adults from Italy. Cases revealed significantly higher scores than controls in two subsets of HO and in two subscales of MAI. Some of these subscales appeared to be age-dependent. The results indicate that particular components of anger-hostility could be taken into consideration when studying psychological risk factors for CHD and EH.

We present here new evidence of cross-cultural agreement in the judgement of facial expression. Subjects in 10 cultures performed a more complex judgment task than has been used in previous cross-cultural studies. Instead of limiting the subjects to selecting only one emotion term for each expression, this task allowed them to indicate that multiple emotions were evident and the intensity of each emotion. Agreement was very high across cultures about which emotion was the most intense. The 10 cultures also agreed about the second most intense emotion signaled by an expression and about the relative intensity among expressions of the same emotion. However, cultural differences were found in judgments of the absolute level of emotional intensity.

The ability to recognize the facial expressions of emotions was investigated in 30 borderline hypertensive patients, 16 with high intralymphocytic sodium content (ILSC) and 14 with normal ILSC, and in 34 normotensive matched controls. To this aim, 48 slides with the facial expressions of emotions and with neutral expressions were shown to the subjects by means of a tachistoscope. Two brief questionnaires, the Affective Communication Test and the Dimensions Rating Scale, were used to assess the ability to express emotions and the intensity of emotional experience in the subjects. Results show in borderline hypertensives a difficulty in recognizing emotions, with differences between the two subgroups of patients.

The present paper discusses the results of classic research on psychological aspects of the hearing impaired and emphasizes the fact that, today, because of the possibility of early hearing aid fitting, the psychological profile of the hearing impaired presents differential features depending upon several factors. In particular, the influence of the mother's education attitude on the psychological reactions to prosthetic rehabilitation and its efficacy depending upon the degree of prosthesis acceptance are analyzed. Finally, the relationship between the hearing aid use and language development is considered.
