Development of a measure of symptoms in chronic fatigue syndrome: The profile of fatigue-related symptoms(pfrs)

Abstract

Chronic fatigue syndrome (CFS) is a disorder of uncertain aetiology which attracts increasing research interest. This paper describes the development of a multidimensional measure incorporating the diverse symptoms associated with the illness. The Profile of Fatigue-Related Symptoms (PFRS) has four scales: emotional distress, cognitive difficulty, fatigue and somatic symptoms. These showed good convergence with comparison measures, high reliability and high internal consistency. CFS patients had markedly elevated scores compared with a student comparison group, and these scores correlated with indices of illness severity. The PFRS is a short and easily administered measure which, it is suggested, may be used to assess patients in terms of the severity and pattern of their disorder, to relate subjective symptoms to immunological and other findings, to evaluate the effects of treatments, and to compare the symptomatology of CFS with that in other fatiguing illnesses.     

Dynamic Selective Exposure during Decision-Making

To understand dynamic changes in the likelihood that people would access and selectively expose themselves to information online, the present study examined the checking of account balances during simulated gambling. Sixteen participants played 120 hands of computer Blackjack for points, at higher or lower levels of risk (different point multipliers), and after each win or loss the computer recorded if participants checked their account balances. There were individual differences in checking rates. Participants who were more likely to check balances exhibited a selectivity of exposure to decision consonant information after a win at low risk. Although it was expected that people would seek to maintain positive mood, data were better explained in terms of Cognitive Dissonance. The effects of Cognitive Dissonance are liable to extend beyond single static decisions into dynamic online environments.     

Departures From Sensible Play in Computer Blackjack

Gambling has been viewed as irrational, and even though blackjack offers rational strategies (i.e., Basic [E. Thorp, 1966] and card counting), people exhibit departures from rationality (e.g., “Never Bust” strategies). To determine whether departures from rational behavior reflect ignorance or fatigue, university students were provided with on-line Basic advice while playing a simplified computer blackjack. Although the on-line advice initially affected the totals these players sat on, it was eventually discarded for higher risk strategies. Irrational play did not reflect ignorance or fatigue and was not necessarily conservative. Real fluctuations of odds in blackjack may lead to situations in which Basic is not perceived by players as effective. Because Basic is not a personalized strategy, it seems less likely to be maintained in the face of losses. Players were more optimistic that they might win when utilizing their personalized strategies.     

African Dreamers and Healers

The author spent five summers in South Africa, doing a cross-cultural study of the indigenous healers among the Zulus in Natal Province, near Durban. She compared the indigenous healers, the isangomas, with a second and seemingly evolving group of healers in the Zulu culture, called prophets. The prophets are connected with a powerful, breakaway Christian movement in South Africa and other parts of Africa that is known as the African Independent Churches or AIC. In this article she shares the conclusions of her research and her comparison of the ways the Zulu healers interpret and value dreams and how Jungian analysts might interpret similar dreams. She sought to identify and understand how the Zulu god-image might be in flux as the Zulu culture is changing in response to other cultures, in particular, the more powerful Western European culture with its advanced technology. Relying on Edward Edinger's conceptualization of the consequences of the destruction of the god-image, she concludes that, in this case, instead of the “cup being broken,” it could be that the “cup is changing its shape.”     

Manipulating Morality: Third‐Party Intentions Alter Moral Judgments by Changing Causal Reasoning

The present studies investigate how the intentions of third parties influence judgments of moral responsibility for other agents who commit immoral acts. Using cases in which an agent acts under some situational constraint brought about by a third party, we ask whether the agent is blamed less for the immoral act when the third party intended for that act to occur. Study 1 demonstrates that third‐party intentions do influence judgments of blame. Study 2 finds that third‐party intentions only influence moral judgments when the agent's actions precisely match the third party's intention. Study 3 shows that this effect arises from changes in participants' causal perception that the third party was controlling the agent. Studies 4 and 5, respectively, show that the effect cannot be explained by changes in the distribution of blame or perceived differences in situational constraint faced by the agent.     

Infants track word forms in early word–object associations

A central component of language development is word learning. One characterization of this process is that language learners discover objects and then look for word forms to associate with these objects (Mcnamara, 1984 ; Smith, 2000 ). Another possibility is that word forms themselves are also important, such that once learned, hearing a familiar word form will lead young word learners to look for an object to associate with it (Juscyzk, 1997 ). This research investigates the relative weighing of word forms and objects in early word–object associations using the anticipatory eye‐movement paradigm (AEM; McMurray & Aslin, 2004 ). Eighteen‐month‐old infants and adults were taught novel word–object associations and then tested on ambiguous stimuli that pitted word forms and objects against each other. Results revealed a change in weighing of these components across development. For 18‐month‐old infants, word forms weighed more in early word–object associative learning, while for adults, objects were more salient. Our results suggest that infants preferentially use word forms to guide the process of word–object association.     

Norms on the gender perception of role nouns in Czech,English, French,German, Italian,Norwegian, and Slovak

We collected norms on the gender stereotypicality of an extensive list of role nouns in Czech, English, French, German, Italian, Norwegian, and Slovak, to be used as a basis for the selection of stimulus materials in future studies. We present a Web-based tool (available at https://www.unifr.ch/lcg/) that we developed to collect these norms and that we expect to be useful for other researchers, as well. In essence, we provide (a) gender stereotypicality norms across a number of languages and (b) a tool to facilitate cross-language as well as cross-cultural comparisons when researchers are interested in the investigation of the impact of stereotypicality on the processing of role nouns.
