When listening to degraded speech, such as speech delivered by a cochlear implant, listeners make use of top-down linguistic knowledge to facilitate speech recognition. Lexical knowledge supports speech recognition and enhances the perceived clarity of speech. Yet, the extent to which lexical knowledge can be used to effectively compensate for degraded input may depend on the degree of degradation and the listener’s age. The current study investigated lexical effects in the compensation for speech that was degraded via noise-vocoding in younger (...) and older listeners. In an online experiment, younger and older normal-hearing listeners rated the clarity of noise-vocoded sentences on a scale from 1 to 7. Lexical information was provided by matching text primes and the lexical content of the target utterance. Half of the sentences were preceded by a matching text prime, while half were preceded by a non-matching prime. Each sentence also consisted of three key words of high or low lexical frequency and neighborhood density. Sentences were processed to simulate CI hearing, using an eight-channel noise vocoder with varying filter slopes. Results showed that lexical information impacted the perceived clarity of noise-vocoded speech. Noise-vocoded speech was perceived as clearer when preceded by a matching prime, and when sentences included key words with high lexical frequency and low neighborhood density. However, the strength of the lexical effects depended on the level of degradation. Matching text primes had a greater impact for speech with poorer spectral resolution, but lexical content had a smaller impact for speech with poorer spectral resolution. Finally, lexical information appeared to benefit both younger and older listeners. Findings demonstrate that lexical knowledge can be employed by younger and older listeners in cognitive compensation during the processing of noise-vocoded speech. However, lexical content may not be as reliable when the signal is highly degraded. Clinical implications are that for adult CI users, lexical knowledge might be used to compensate for the degraded speech signal, regardless of age, but some CI users may be hindered by a relatively poor signal.

Commentary on Quwaysinī's commentary on Akhḍarī's work titled the Sullam al-muawraq on logic.

The general question to which Edwards here addresses himself is "whether any event whatsoever, and volition in particular, can come to pass without a cause of its existence," and among other arguments for a negative answer he has a reductio ad absurdum, arguing that if an act of will can occur without a cause, then anything at all, no matter how fantastic, can occur without a cause. There is, he says in effect, an inner contradiction in the notion that uncaused (...) events are bound always to be acts of will. We must note, however, in following his argument through, that his language is not quite that which I have just used, and in particular he does not speak primarily of what "occurs" but rather of what "begins to be." He says. (shrink)

A. N. Williams examines the conception of the intellect in patristic theology from its beginnings in the work of the Apostolic Fathers to Augustine and Cassian in the early fifth century. The patristic notion of intellect emerges from its systematic relations to other components of theology: the relation of human mind to the body and the will; the relation of the human to the divine intellect; of human reason to divine revelation and secular philosophy; and from the use of the (...) intellect in both theological reflection and spiritual contemplation. The patristic conception of that intellect is therefore important for the way it signals the character of early Christian theology as both systematic and contemplative and as such, distinctive in its approach from secular philosophies of its time and modern Christian theology.
