The Obelisk is a supernatural thriller that’s filled with intrigue, drama, romance, action and adventure. Life had recently become very interesting for Dr. David Sholfield?a new town, a new career, a new love interest. The happiness he felt at joining Dr. Lucas’ renowned surgical team at Northwestern Memorial Hospital in Chicago was only eclipsed by meeting the lovely Angela Stockman, a college professor at Columbia College. Angela’s friend and fellow professor, Tom Harrison, who she brought along on their first date, exhibited certain eccentricities, leading David to the conclusion that he, as well as Angela were harboring secrets, and he was determined to find out what they were. As David continued dating Angela, he learned one of her secrets, that she was heiress to the fortune of a wealthy real-estate developer. David noticed, during several outings at Angela’s parent’s mansion, that Tom Harrison’s behavior continued to deteriorate, culminating in a psychotic episode at a 4th of July celebration at a European Aristocrat’s mansion. When David visited him in his hospital room the next day, Thomas asked him to retrieve a cedar chest, located at his parent’s cabin in West Virginia. Out of sympathy, David agreed. Unfortunately, when he returned, Thomas was dead, having passed away under mysterious circumstances, leaving David in possession of the chest, which contained two books written in a strange language. After the books were translated, David learned that one of them was the memoirs of the now deceased Thomas Harrison. The information he gleaned from Tom’s memoirs changed his life forever. David knew that he had to make the most important choice that anyone could ever possibly have to make. He could either dismiss the writings as the hysterical ravings of a madman, or he could try to discover if the information contained in them was true, because if it was true, it would be the most important find in the history of mankind.

Lo scopo della psicologia dello sviluppo è descrivere e spiegare i cambiamenti nel comportamento e nelle attività psicologiche dal periodo prenatale fino alla vecchiaia. Il volume affronta in modo approfondito i principali temi della psicologia dello sviluppo dal periodo prenatale fino alla vecchiaia, esaminandone sia gli aspetti biologici che quelli culturali. Nel testo sono presentate le più importanti teorie dello sviluppo in una prospettiva storica e, in particolare, quelle di Piaget, Vygotskij e Bowlby, che permettono di comprendere gli orientamenti della ricerca contemporanea e forniscono una sintesi moderna rispetto alle radicali posizioni innatiste e ambientaliste. Il testo presenta inoltre recenti ipotesi, sostenute da evidenze sperimentali, che hanno portato a parziali revisioni di queste teorie. Il volume fornisce in tal modo una visione complessiva e aggiornata delle questioni teoriche e metodologiche più rilevanti della psicologia dello sviluppo ed è consigliato per studenti universitari, insegnanti, operatori del settore, genitori e per tutti coloro che sono interessati a questa disciplina. l curatore di questa edizione ha inoltre apportato integrazioni e adattamenti specifici per il pubblico italiano. A tal fine, sono state anche illustrate recenti ricerche italiane rilevanti per i temi trattati nel testo.
