Family context of infantile colic

Psychological factors in families with a colicky baby were studied. A total of 59 families who had enrolled on the basis of information received at the postpartum wards in the city of Turku, Finland, were included in this study. In addition, 58 families with age-matched infants were selected as a control group. These families kept a diary of the infant's crying. Thirty-six infants fulfilled the criteria for severe colic. Twenty-three families with a baby who cried excessively but did not fulfill the criteria were defined as the moderate colic group. A semistructured family interview was carried out to assess the structure, communcation patterns, functioning, and affective tone of the families. Mothers and fathers were younger in the moderate colic group compared with parents in the other groups. In the moderate colic families, the infant was more often the first child than in the control families. On the other hand, neither the infant's gender nor the education of the parents was related to infant's crying. Organized family structure and strong parental coalition were more often present in the severe colic and control groups than in the moderate colic group. Increased family chaos was noted in this group. The severe and moderate colic families had more enmeshed individual boundaries. Generational boundaries were enmeshed in the moderate colic families. Communication patterns did not differ between the groups. The families with a severely or moderately crying baby were less flexible, had decreased ability to cope with daily activities, and showed less energy and vitality than the control families. Both the severe and moderate colic families expressed more anxiety and conflict compared to the control families. In conclusion, an association between infantile colic and psychological characteristics of the family was found. Moreover, the families with a moderately colicky infant had specific psychological features that differed from both the control families and those with severely colicky infants.     

Subjective probability intervals: how to reduce overconfidence by interval evaluation

Format dependence implies that assessment of the same subjective probability distribution produces different conclusions about over- or underconfidence depending on the assessment format. In 2 experiments, the authors demonstrate that the overconfidence bias that occurs when participants produce intervals for an uncertain quantity is almost abolished when they evaluate the probability that the same intervals include the quantity. The authors successfully apply a method for adaptive adjustment of probability intervals as a debiasing tool and discuss a tentative explanation in terms of a naive sampling model. According to this view, people report their experiences accurately, but they are naive in that they treat both sample proportion and sample dispersion as unbiased estimators, yielding small bias in probability evaluation but strong bias in interval production.     

The effects of background noise on dichotic listening to consonant-vowel syllables

Lateralization of verbal processing is frequently studied with the dichotic listening technique, yielding a so called right ear advantage (REA) to consonant-vowel (CV) syllables. However, little is known about how background noise affects the REA. To address this issue, we presented CV-syllables either in silence or with traffic background noise vs. 'babble'. Both 'babble' and traffic noise resulted in a smaller REA compared to the silent condition. The traffic noise, moreover, had a significantly greater negative effect on the REA than the 'babble', caused both by a decreased right ear response as well as an increased left ear response. The results are discussed in terms of alertness and attentional factors.     

Adaptive changes between cue abstraction and exemplar memory in a multiple-cue judgment task with continuous cues

The majority of previous studies on multiple-cue judgment with continuous cues have involved comparisons between judgments and multiple linear regression models that integrated cues into a judgment. The authors present an experiment indicating that in a judgment task withadditive combination of multiple continuous cues, people indeed displayed abstract knowledge of the cue criterion relations that was mentally integrated into a judgment, but in a task withmultiplicative combination of continuous cues, people instead relied on retrieval of memory traces of similar judgment cases (exemplars). These results suggest that people may adopt qualitatively distinct forms of knowledge, depending on the structure of a multiple-cue judgment task. The authors discuss implications for theories of multiple-cue judgment.     

Health examination and scientific inference in occupational health service

In spite of doubts in many quarters there seems to be considerable confidence in the benefits of health examinations. In my opinion it is important to analyze the structure and the purpose of the examinations in order to elucidate the practical thinking and logical quality of OHS. In this article I will conceive health examination as an information process and offer types of inference, i.e. prediction, abduction and induction, feasible for the analysis. I will study the logical conditions and possibilities to draw conclusions using these inference methods and try, in a preliminary way, to show how the qualitative or quantitative formulations of presuppositions affect the formulation of the conclusion. Finally I will explicate the implicit purposes of the health examinations stipulated by Finnish legislation with the aid of the above inference methods. I find the methods feasible for analyzing the information process, and will set forth some conditions for presuppositions used with inference and point out the alternative purposes of Finnish occupational health examinations.     

Relative alpha desynchronization and synchronization during perception of music

Relative desynchronization (ERD) and synchronization (ERS) of the 8–10 Hz and 10–12 Hz alpha freqency bands elicited by music were studied in ten musically untrained right-handed subjects. The subjects listened to two five-minute musical excerpts representing two different musical genres, popular and classical, presented both foward and backward. ERD/ERS of the two alpha frequency bands was examined during the first four minutes of stimulus presentation using one-minute time windows. The results demonstrated that both the 8–10 Hz and the 10–12Hz frequency band exhibited reactivity to musical stimuli. The responses of the 8–10Hz and 10–12 Hz alpha frequency bands were dissimilar, dymanic and dependent on both time and stimulation type. The dynamics of these changes over time may explain some discrepancies in earlier EEG studies during listening to music.     

An experience sampling study of emotional reactions to music: listener, music, and situation

The Experience Sampling Method was used to explore emotions to music as they naturally occurred in everyday life, with a focus on the prevalence of different musical emotions and how such emotions are related to various factors in the listener, the music, and the situation. Thirty-two college students, 20 to 31 years old, carried a palmtop that emitted a sound signal seven times per day at random intervals for 2 weeks. When signaled, participants were required to complete a questionnaire on the palmtop. Results showed that music occurred in 37% of the episodes, and in 64% of the music episodes, the participants reported that the music affected how they felt. Comparisons showed that happiness-elation and nostalgia-longing were more frequent in episodes with musical emotions, whereas anger-irritation, boredom-indifference, and anxiety-fear were more frequent in episodes with nonmusical emotions. The prevalence of specific musical emotions correlated with personality measures and also varied depending on the situation (e.g., current activity, other people present), thus highlighting the need to use representative samples of situations to obtain valid estimates of prevalence.
